It almost entirely depends on your internet connection. There's a couple of sites you can test it on but in general for a basic bottom range DSL/Cable connection 3 to 4 people connecting from the internet is pushing it. If your on a local Lan then your ram and power of the computer that's hosting the Server is the main ingredient. I have 4gigs of ram (I have a total of 12gig on the computer) dedicated to the server and I have 4 family members playing without any problems at all, wireless and ethernet.

No, many users cannot be logged in the same time. Only server OS can do that. There are some "hacks" which you can do with your Xp to allow many terminal sessions in the same time. Which includes replacing some dlls with ones from Windows server 2003, and editing the registry. If you mean many users access to shared folders or printers, then the answer is yes. You can do that without any "hacks".
