internet cafe & Knoppix

Is it possiable to run an internet cafe with knoppix? I'm doing research to help my wifes brother out who bought an oooold internet cafe off some guy for the cheep and got what he paid for. The thing is I consider myself pretty good with computers but have never run an internet cafe let along set one up. Running the hardware is simple and setting up the router is no problem I'm concerned with the software side. What I'm planning on doing is setting him up with new hardware and possiablely <-spelling? getting him a new place to setup his computers instead of using his house. This a a beginning of a vision I have of a multifloor place with xboxes on one floor and computers on the other with a coffee bar to the side. I'm getting off the subject but anyway is this possiable? Thanks for your time Phillip
