Portrait of obscurity

Those clever and passionate guys over at VoIPUser have been posing the question - whatever happened to Microsoft's Portrait, which on the surface seems like a natural contender in the video VoIP field. It talks SIP and interfaces with MSN Messenger, runs on a variety of devices, and claims to adjust image quality and frame rate to bandwidth conditions. If anyone (particularly anyone from MSN) can share any insight into where this is heading (or not, as the case may be), give us a shout.
