Absolutely!  Fortunately, this is already built into the architecture :)

If *your* server doesn't offer a particular transport/feature that you'd
like to make use of, all you have to do is find a public one.  All
transports can optionally have public IP addresses to access them.

So say you weren't running the @ICQ transport locally, but xyz.com was and
allowed the public to use their installation.  They configured the ICQ
transport to be icq.jabber.xyz.com, so you just use @icq.jabber.xyz.com.

Everything is configurable as to how this works, but all the posibilities
are already there.

This is also an excellent idea.  How I'd see this working easily would be
a special authentication module for the Public Server above, and that
module contacts the backend authentication system.  This is all very very
