Scarce objects -- bearer certificates for usage control

[R. A. Hettinga]

Yup, certainly anyone who's thought about paying for, say, grid networks
time, or wireless access, has at least plinked around with the subject, but
it's nice that someone like *Nick* is thrashing some cycles on the problem.

In the interest of "telegraph, telephone, tell Hettinga", I'm just sending
this along and will read it myself later.

Cheers,
RAH
