Compression is still hiding the data and I would say breaks the rules.
Better solution: use SSH. You can have public key authentication (no
cleartext passwords) without any encryption or compression.

telnetd usually starts from inetd, but inetd doesn't seem to have a way
to only listen on certain interfaces. You could use TCP wrappers (ie
/etc/hosts.{allow,deny}) to limit the IP addresses which are allowed to
connect to ones which you know will be on the radio interface.
