<p>Ah, here's what I was trying to get to last night.  Unfortunately, I 
wasn't on the top of my game.

I'm not arguing that this information isn't interesting or useful. 
There are just too many variables to expect the tag to give any reliable 
information.  Consider this.  In a matter of minutes, I could pull down 
the source for vorbis, hack up a new library (a la GCP, only in a very, 
very *bad* way, because I'm an idiot when it comes to audio coding :), 
I'm also ignorant, so I fail to change the vendor string in the library 
(I'm guessing that its hard-coded), encode a few CDs with "-q 7", share 
them on a P2P.  What'll you have now?

The information would mostly only be reliable if you keep the files to 
yourself.  In that case, set your own personal standard.
