[vorbis] Ogg bitstream spec question

Mike speaks for himself, but I'm sure we all agree on the issue here:
it would be a bad idea to change the spec *just* to make implementation
easier.

The goal of Xiph.org is not to make free software, but to make an
open, free, libre, whatever, audio (and other multimedia) standard.
Free software is only (a part of) a means to an end here.

Of course, having free implementations is a good thing -- but it is
*not* the goal.

[I don't speak for Xiph, btw -- this is just my understanding of matters].

I don't think it would be all that useful -- Ogg is a transport-level
layer, it would need more semantics for Ogg-in-Ogg encapsulation to
be useful.

Vorbis-*on*-Ogg, not *in* -- Vorbis is a different semantical layer.

<p>Anyway -- if you really want to encapsulate Ogg in Ogg, it's obvious what
the semantics to do so are, so go ahead -- although I think it would be
wasting your time.
