Using telnet is not a good idea. Telnet is provably insecure -- it is a 
great big security hole. ssh is a better solution for machines which are 
on any untrusted network.

An even better solution would be to use a library like Pyro or rpyc for 
executing remote procedure calls.

I strongly recommend you use an existing solution rather than hack 
together your own.
