The server won't be streaming any audio/video or anything crazy like that, it's just going to be for storing files. When we want stuff, we just copy it to our computer and run it from there.

And as much as I'd like to have a wired connection, most of the people in residence have laptops, so wired connections wouldn't work too well. Although I'm pretty sure the wired & wireless connections are on the same network, so I suppose I could theoretically have the server wired, and have people connect to it wirelessly, but of course that wouldn't do much to reduce the bottleneck...

I looked at Samba, and it seems to fit the bill, and the most recent version seems to have added support to work with Vista, according to the link above...
