I thought it'd be as easy as her plugging into my switch, enabling DHCP, and it'd work, but we actually had to go through quite a hassle... turns out we were plugging a cross over cable into my switch. duh. plugged in a normal cable and it all worked fine. heh. :-)
update: haha ... i put vnc on her computer, so now I can use x2vnc over 3 monitors.... :-) we're installing linux on her desktop computer this weekend, so she'll need vnc eventually anyway, so it's not like i'm entirely devious. (well ... actually I am. but revjim and I can't talk about that)
