Have I contributed enough bits to
this forum that I can ask for some
in return?

i.e. would somebody (perhaps the
author of "Capturing the state
of Distributed Systems in XML" himself) please
research "Coins" a bit and tell me whether
I should spend some serious time investigating
it? I looked briefly, and it didn't seem
too far fetched.

(last time I sent a "please review"
message, I got some pretty good clues.
FoRK works pretty well as a PICS
label burea/SOAP service.
But I don't know what my cluon balance
in this forum is lately. Am I allowed
to go into debt?)
