[ID3 Dev] PCNT question

[Dan O'Neill]

Hi Timothy,

It's like mostly my fault for not having a more collaborative wiki setup 
that enables discussion and revision of the spec.  I've been busy with 
my day job (http://trusonic.com) over the last year.  New hardware and 
software and stuff took up a considerable amount of bandwidth.  I *will* 
make some changes over the next month to enable this spec to get fixed 
by those who want to contribute. My apologies to the entire group.
