Interesting. Of course if the card is just a capture card then you would
have to encode the component video in real time, or store a LOT of
information, something even the fastest general purpose computers would
have a hard time doing. It would probably also push the disk I/O of
consumer grade equipment pretty hard.

Obviously it will be possible sooner or later, and somebody has to be
the first to dance, but I question is sub-$1K cards would be usable with
present home PCs.
