oh, and I'm also trying to make the switch over from Windows Linux Ubuntu so could I also do this in Ubuntu?
I've read a few examples of what it can be for, but I couldn't find whether or not it could be used to directly link two computers instead of wireless. Could it? I'm trying to see if I can watch the tv episodes saved on my mom's computer on mine without having to copy them over every time. An ethernet connection is going to be much faster than wireless so could I somehow make this work? She has Vista, and I have XP.
