On the contrary, someone wrote me privately that there is a new AS/400 telnet
server that uses SSL.  Plus, the same person indicated that there is already
encrypted password authentication built into the (newest - 1) version of the
AS/400 telnet server.  You can read some RFC's that propose that authentication
(links on the tn5250 developer site).  Obviously things have progressed beyond
the proposal stage.

Sorry that you misunderstood.  Clearly the encrypted link I was talking about is
the one between the Linux proxy and the the java client.  As you say, what would
be the point of encrypting a connection between a local proxy machine and the
AS/400?

Based on the new telnet server information above, it may be possible to encrypt
all the way through the proxy to the new telnet server.  But, for those AS/400
sites that have not upgraded, an encrypting proxy server would still be useful.
