A po' man's solution would utilize forwarding. It would add a layer of complexity (keeping the tunnel up between the machines), but may solve your problem rather simply until SSH support is added.
ssh -L 6666:remote.machine.com:23 -l username remote.machine.com
would open the SSH session that will forward the traffic.
telnet 127.0.0.1 6666
Will connect to the remote machine.
Be warned however, this may not solve your problem, if there isn't a telnet daemon at all... but most sysadmins would be willing to work with you in this matter. It would still meet most security requirements if telnet is only listening on the loopback interface.

easily use ssh in your apps.
