Thanks, that's the sort of thing I was looking for, but as you say, it
would be really useful to be able to run it on your own keyring honouring
the trust levels you assign.

Since the update-trustdb algorithm for gnupg must perform all the
necessary calculations, I'd have thought that it shouldn't have been too
difficult to modify the same algorithm to trace the path to a particular
key (theoretically, anyway ;-) ).

Do you know if the source for gpgwww.cgi is available anywhere?

All the best,
