I have a G5 and a PC connected via a router. Plus there are PowerBooks that communicate via their internal Airport cards and the router. I can connect to the internet from the PowerBooks. BUT I have not yet found out how to make the PowerBooks communicate with the G5. Anyone know how to make the PowerBooks communicate with the G5? ALSO: can I remotely from one of the PowerBooks (or even from the PC) modify a document (e.g. add text to a Word document) that is on the G5?
