[vorbis-dev] WAV header (hey Mike)

People are allowed to use any arbitrary chunk.  Often "JUNK" is used to pad
out fields but never make an assumption that a chunk is in a fixed place or
that it exists (other then DATA).

Also when you write out and ogg file please use the "FACT" chunk that stores
the number of samples in the original file.  

On an unrelated note are there redirector files for Ogg streams? (i.e. .pls,
.m3u, .asx...)

I'm not sure it's so much a matter of allowing any arbitrary chunk type as
it is peopl enjoy writing software that uses arbitrary chunk types.  What
is in the spec is that players should ignore any types that they don't
recognize (as opposed to dying, I suppose)
