it takes a fairly decent computer to run a server well, you should do fine with buisness class dsl (same up and down) not too sure how many connections thats good for, but it should be good for about 24. if dsl doesnt do it for you a t1 line will cost about 200 bucks a month and i dont know of any comercial device that will connect to a t1, so you have to get a router, the cheapest i know of that will do it is 800 bucks. and you have to know how to configure a cisco router.
how do you shoot the devil in the back? what happens if you miss? -verbal
