A GUID provider has to prove persistence by being persistent ? So we
would need a _certified_ watchdog ;)

It depends on the audit method, if you take a look at the criteria for
long term archives there surely are several criteria a one man band
would never meet. But if you think of long term persistence (>decades)
it is most likely that a one man band will not be able to ensure
persistence - at least not beyond the lifetime of this person..
Btw. I forgot to mention the _english_ TRAC list of criteria
(http://www.crl.edu/PDF/trac.pdf) in my blog.
