That very well could be.  I'm figuring that there will inevitably be 
some users out there who are behind an improperly configured router or 
firewall, but for the most part I would like to help to ensure that my 
program will be usable by any user.

I have been doing a little research and it appears that there is really 
nothing much that I can do to forward a port on my own, but instead I 
have to rely on the user figuring out how to do it on their own... which 
does not help me at all.

I do have one question (and please don't throw me to the wolves if I've 
proposed to break the "network" law), but where is the harm in my 
program utilizing a port that is most likely being forwarded?  If I 
utilize port 110 (POP3) behind a router, will the outside world still be 
able to communicate with me?  I'm not on a router right now so I can't 
try it out on my own.
