I set up an
IBB installation for some friends and it seems to work well for them, well, they don't complain to me about it anyway. They had over three years of problems with eircom before they moved.
I don't see the point with running desktop as wireless. You end up sharing your wireless bandwidth with a static machine. I know this from experience because my Dad insisted on using two desktops wirelessly and, yeah, it works but why bother. Wired is more secure and runs faster. You will notice the limitations on 54Mbit when you transfer large files or when your network computer updates the same software at the same time.
