This is an idea I have been mulling over a bit.

An recieptionist (an object), that is reachable via an sturdyref, recivies an sequence of authorization certificates.

An certificate is an tuple of issuer, instructions and signeture of those two by the issuer. An issuer in above is simply an public key (or fingerprint of the key to identify it). The private key counterpart of that key is used to sign the certificate.

The recieptionist has an mapping of issuers to avatar objects.

For each certificate in an sequence
  the recieptionist checks the signeture of the certificate
  if invalid then an exception is thrown
  the recieptionist then checks if it has an issuer to avatar mapping
  if not then an exception is thrown
  then the recieptionist invokes the avatar object and passes it the instructions in the cert
  the avatar object then interprets those instructions as its programer sees fit.

An facet of the recieptionist handles introductions of new issuers and construction of avatar objects for those issuers. (Some such introductions wouldnt out live the session of the current sequence).

One type of certificate would be an online challange-response requesting certificate where an capability to the requester would be passed to an avatar object if it succeeds.
