Paths of trust in PGP

There is a really cool service being offered on the web. It allows users to trace the paths of trust between two keys in the PGP world. It is worth checking out: http://www.research.att.com/~reiter/PathServer/ This is a good way to find the paths you want in the web of trust. For example, you can type in your key id, and the key id of a new, candidate key, and you will find all of the signature paths from your key to the new key. You'll be surprized at how connected the graph is. Avi
