I don't think an encryption of your password would be illegal.  As long
as you ID'd yourself unencrypted anything else could be considered your
"data" and as such wouldn't have to be in english.  Besides, you don't 
want to have a password scheme on a radio system.  You'd want a system
that was interactive.  The host would send a data stream to the terminal,
the terminal would transform the data stream by an equation or algorithm
that is unique to that terminal and known only to the terminal and the host,
then transmit the modified data back to the host.  The host would then
check to see if it was the correct transformation.  By using short data
streams with complex algorithms the code would be virtually unbreakable.
You could even have it "re-id" anytime the link is brought back from an
idle state of say more than 2 minutes, and in any case, every few
exchanges.

I think the only legal issue is the business use.  You could use it for
"notes", personal mail, and "home"projects but that would be it.
