Answers.Text: I purchased an Intensity Shuttle. It is **very** finicky. You must be running Windows 7 (not older, not newer) on a specific USB3 chipset with a sufficient amount of bandwidth (older computers will not work) and you must use a specific resolution/frame-rate otherwise you'll get a black screen. Assuming you get past all these hurdles, it'll work (at least under Skype).

Any capture device that has [WDM Video Capture](http://msdn.microsoft.com/en-us/library/windows/desktop/dd373405%28v=vs.85%29.aspx) support will work as a web cam input.  Something like the Matrox MXO2 Mini would be one device that has such support and would get the job done, but it is PCI-e or thunderbolt.

Comments.Text: @AJHenderson, Yes, USB3 is a hard requirement because the PC will likely be a laptop or tablet that does not accept add-on cards. I might be able to use an ExpressCard slot with the MXO2 but I'm holding out for a USB3-only solution for now.

Comments.Text: yeah, I'm not aware of anything that is capable of doing what you need over USB3.  As I understand it, there are architecture issues that make USB architecture in general not really work well for such work.  I have not looked seriously in to it since USB3 came out though.
