Sounds like a good solution but it also sounds like a certificate signed
by the JSF. We come back to the signed certificate need. Whether the JSF
should or should not be an authority able to sign certificate is not
really the problem, the problem is : should we require signed certificates ?
I think it would be a great solution for both full XMPP adoption and
SPIM problem. It just raises the problem of defining a list of trusted
authorities. Some of those authorities should of course be free of
charge (CACert, etc.).
