We're mostly in agreement, but for the record I've always had a hard 
time believing that URNs will actually be more reliable/persistent in 
practice; the causes of URL breakage are mostly incompetence and 
stupidity, and a guaranteed level of indirection may not succeed in 
routing around this.

Yeah, the MS Office practice is really egregious in my view.

Aha! Thus we can disband the TAG and most of the W3C and the IETF HTTP 
work and turn all the work over to the URI group and go back to writing 
code and taking vacations.  I *like* this approach:)  -Tim
