I will say that your internet should be half way decent though. Also if you plan on hosting on one computer and connecting from another through a lan line ensure that the lan won't interfere with the internet speed. My set up can host 3 people, plus me lan connecting before people experience a bottleneck.

I am not an expert network person, heck I have trouble following the lego instructions of putting a tower together, but if you have some one who can set up a good network with privileges priorities and all that fancy stuff I won't even try to say because I'll just look stupid.
