I need to build an application that meets the requirements below. It can be a windows client, silverlight client or WPF client.
Screen will show video stream from 2 separate cameras in 2 separate windows
Need to have PVR type functionality that is...
2.1 Show Live Stream
2.2 Pause and playback previous 30 seconds of video
I'm trying to use resources I have that is C# application development however I don't have any experience with video capture.
Any help in terms of Libraries I can look at or the best way to do this.
Thanks

Mainly you will need to use DirectShow.
Here are useful links :
Camera Vision - video surveillance on C#
DirectX.Capture Class Library
Capture Live Video from various Video Devices.
C# and VB.NET Webcam Library and Sample
Also sometimes web cams are coming with the SDK, check for it.

I am supposed to design an application for a large multitouch screen. By large, i mean newscaster large (around 55 inches and above). The application is an interactive map.
My questions is: which technology to develop the application in. My first idea was to make it in Adobe Flex, but then there is HTML5 too...
There must be some awesome Java library for touch interactions too, but then on Windows platform there must be C# library too?
Could someone please point me in the right direction.
The backend is probably going to be in Java EE.
Is there a specialized touch maps sdk?
Why reinvent the wheel?
Ventuz hands down best touch software I have used and I use it daily. It's specifically for large multi-touch presentations.
If you are looking to build it yourself, you will have a long long way to go. Ventuz is extremely flexible and will let you do anything you'll need to do with touch for the most part.
(And they are based in Germany, like you)
Here are some demos they showed last year at NAB

Currently debating on using Xamarin for a project, anybody got any ideas on android billing system? ideally on the subscription service. Is it all done through play store?
In-app billing requires sending requests from your app to IInAppBillingService. This requires using an AIDL file to invoke IPC method calls, but it is currently not supported by Mono for Android. However, it is still possible use AIDL in Mono for Android, but need some workarounds. Take a look at this answer.
Also, I heard there are some existing solutions to do in-app billing, check this or this.

Is there any way to implement the OpenGL on the Silverlight? We need to create a web browser application to load an OpenGL 3D image and to perform rotation and zoom functionality. We can easily load the OpenGL component in a WPF windows application. But it is not allowing to load the OpenGL in to a Silverlight application.
If Silverlight doesn't support OpenGL, what is be the best choice to create the web application with OpenGL 3D?
Silverlight does not support it, nor will it in the future (Silverlight is discontinued!). Instead for cross-platform graphics you could go with WebGL, but it isn't implemented in every browser yet but seems to be the future.
To clarify, Internet Explorer does not support it (Big shocker!) while Safari and Opera do have it, but need it to be enabled by the user prior to it working. There is no other true cross-platform way to deploy OpenGL on the web at this point.

Basically we're looking to develop a relatively simple application, but we only want to do it once. We're a .net development house. As that is our strength, we'd like to stick with that.
I've seen Mono for Android (http://xamarin.com/monoforandroid). Is this good? Does anyone have experience using this for both Android and iPhone?
Mono for Android will only allow you to develop Android apps, not iPhone apps. For iPhone apps, consider using MonoTouch. I don't have any experience using these, but keep in mind that they are not free.
Writing a port application from an existing application is not that hard if you know the language. You can rewrite a .Net application easily for Android if you know Java. There is no universal framework however with full native power.
I never try mono On a mobile device,but on the other platform it works not bad.
And there are some apps online now.

I've been asked to write an internal application for our business that uses mapping functionality to place push-pins of business related data.
As this is not a public facing application and to be used by a single person within our firewall I can not use google maps as we do not have the funds for the google license.
I am investigating the use of OpenStreetMap and can either embed a component into an already existing WPF application or embed into an existing WPF application, a NetBeans platform based application or into a new web application.
Could someone please suggest a library for use in either of these environments?
I recently updated JMapViewer from r26523 to r26975 without incident. Subjectively, it seems faster.
I've recently started to build a WPF prototype using SharpMap - although it's currently migrating to V2 and some of the dataproviders are missing - so I've been using V1 which has support for BruTile. You also might find BruTile useful.
