Ah okay, I read your e-mail as a whole as saying "there is at least 1 player that supports it". I would think there is some alternate interface that could be plugged in to XvEnc or perhaps via gstreamer though since I think most graphics cards in PCs know how to do some video decoding. Nevertheless, Flash on UNIX doesn't use XVEnc or even XVideo (there was an Adobe blog post awhile back as to why they didn't use XVideo).
The "Sun Ray people" could help fix the problem by exposing the XVEnc API, though I suspect that's not really in the hands of the engineers. As it is currently a closed API, the only people that could theoretically start using that interface on UNIX would be employees at Sun who had access to both the API spec and worked on developing a player as well. Either that or someone else will need to reverse engineer the protocol.
