My original thought had been amature, although in reality I'm open
to anything faster than 56K which will work in a point-to-point setup,
almost line of sight, over 10ish miles.

Can anyone nail down a price for this sort of setup?

We started with the Cygnus Kerberos 4 package (ftp to ftp.cygnus.com,
and you'll find a file which decribes how to prove you can legally
aquire the software and how to get it after that) which is MIT
Kerberos 4 ported to a variety of Unix architectures (including Linux)
and setup to use GNU configure. We added support for multi-homed
machines, and I changed the server and client code to handle authentication
over both TCP and UDP protocols so we can authenticate through other
peoples' firewalls which block UDP. We then setup our firewall to block
telnet, rlogin, and klogin services; and only allow eklogin.

No idea; although you can do this at an application level with the
kerberos rlogin and eklogind.
