I think the issue here is that was need some way to refer to 
particular substreams in the Ogg stream, the way Skeleton
does. <video> presumedly always refers to a video/ogg stream
in our application, and even a video/theora stream since it's
an internal reference. But what if there are multiple multiplexed
video streams.

A URI/URL scheme for referencing streams would be a generally useful
thing. Should we override the query mechanism like the time fragment
draft? "?oggserial=0x15323421" ?
