In practice, how do we make that happen? On the XMPP network we're
pushing to make sure that all client-to-server and server-to-server
hops are encrypted (yes, I know, per-hop encryption is not enough, we
need end-to-end encryption too). Is there a handy list of PFS-friendly
ciphersuites that I can communicate to XMPP developers and admins so
they can start upgrading their software and deployments?

Thanks!

Peter
