For the second protocol, <a href="http://www.jabber.org">Jabber</a>
might be just the thing.  The best part about Jabber is the real time
messaging capability, and if I was designing the second protocol, I would
include this functionality.

I don't believe there are any Jabber clients/servers written in Ada, and
I'm not sure how well Jabber uses crypto, but I do know that I still
miss a useful ICQ, and AIM doesn't fill the void (can't do computer to
computer messages in AIM.  They must go through the central server).
