The problem will be two fold (and likely more), but a lot of that depends on what remote device (or Thin Client) you are using. First comes the current compatability with the webcam itself on the remote OS, and then not to mention the performance of the USB device back to the VM. The second issue is the multimedia performance on the remote device. Although a lot of multimedia enhancements are already out for VDI and other similar implementations, it still isn't on par with a local workstation. On top of all of that is the fact that RDP is not bi-directional for audio by itself. I believe some companies have allow for modifications or add-ons currently to allow for RDP audio in both directions.
Although it may be possible to configure something with multiple solutions/vendors. I don't think the available technologies are at a point that it would work right now. For what it's worth, we asked the very same questions about a year ago when first configuring our environment. Things have definitely progresses since then, but I don't think we are there just yet.
Thanks
