I'd suggest taking a look at Twisted, which contains a more complete
telnet implementation (not as important for being able to launch vi),
an ssh implementation (which you might want to use instead of telnet),
a VT102 implementation (which is actually what will help you run programs
that want to fiddle around with the cursor in fancy ways), as well as a
fair amount of work towards a simple terminal emulator (to help you keep
track of what vi has done to your virtual terminal).
