This is a good point... I wonder what the implications are for
interoperability - UUID based URNs do make a hell of a lot of sense
for this environment.

Oh and before I forget, so I wanted to release OCCI under CC with a
view to pulling directly from Sun, Google, etc. but it was shaping up
to be a battle with the OGF board. May revisit the question with them
later. CC licenses exclude trademarks and patents so in addition to
copyright there's trademark and patent protecion for us to think about
(Sun's TM is less of an issue but not sure there was a patent
license/pledge for it). That said it's amazon who appear to be the
resident experts on IP problems.
