run it off your private PC, in fact, many here do.. but this will severely
limit you as your home connection is not going to allow any more than a few listeners on at the same time.. Also, setting up the server on your box is "tricky" at best.. and its recommended that the "broadcasting server" NOT be behind a router.
If you have your own REAL
T1 or better connection and you have a PC directly-connected with its OWN non-shared STATIC IP
then thats a whole different situation altogether!
