I'm not aware of anyone who does this currently but it should be
(unlike the case with Vorbis) straightforward. Theora has some setup
data in the first three headers (look at the vorbis rtp draft or the
matroska spec for ideas on how to pack that into a single binary
blob). After that it's one variable-sized compressed data packet per
frame, so as long as you build an index table you should be fine.
