[Twisted-Python] Telnet server example?

[Britt Green]

Hey!

I've studied the chatserver example a few times. I suppose I probably
didn't initially define my question as well as I should have. If I'm
writing a program like a chatserver, or whatever that takes
connections over telnet, is it better to use the Telnet lib or just
use Protocol?

Cheers!

Britt
