Wireless Networks

Is there any particular reason why you sujest that Clininc Office XP should not run over a wireless network? I am currently looking at this application as a management solution I am building for a family friend in his physio practice. They currently have 2 pc’s that will run the management system, plus am looking at a tablet pc to use in the treatment rooms to make the booking of appointments more user friendly.
Also would you be able to tell me the best way to set up the system, I would like to have access for 3 users at any one time using the same Clinic Office database.

Many Thanks Guys
