I haven't jumped into POE myself, but in trying to decide if/when I
should, I did find this tutorial:

http://poe.perl.org/?Evolution_of_a_POE_Server

It shows a simple TCP server -- written the hard way.  Then it
gradually swaps out pieces of it with POE components using greater and
greater levels of abstraction until the final program is quite small
and elegant.  It's both a good tutorial and a good argument for why to
use POE.

I think it will help you regardless of whether you ultimately choose
to use POE or not.
