You need whatever "password" (whether hashed or not) the client sent in
order to combine it with the stream ID to match their digest. So to do
the transformation server-side, you'd have to use a reversable
conversion (rot13, base64, etc), which is pointless.

I agree with Dave - this adds ONE thing, the ability for servers to
store encrypted passwords. No, its not going to add additional wire
security - thats not its point.

If you want something thats simple to implement and doesn't require much
effort, use what we already have, or use this extended version. If you
want something better, use SASL and/or TLS. If none of that suits you,
then perhaps you should have thought about bringing it up while the XMPP
work was in progress - its not like its just appeared out of nowhere.
