I don't know; I'm not familiar with many uses of UUIDs, either.  I'd expect 
some messaging protocols might be able to use such a thing, but an argument has 
been made against email/news message-ids using them.  Just pointing it out, in 
case anyone is assuming uuidgen will always give something suitable for 
exposing to the net at large associated with one's identity.

Are calendar or org files not suitable for being made public?  (That's a 
serious question; I don't use either one.)  Should they include information 
that helps track what computers I use?
