undefinedundefined Hi, I currently own a PowerBook G4, an iBook G4, an iMac G4, and a Desktop PC. They are all set up wirelessly (airport extreme) and working fine. Now, I know there are some features and benefits of being on a LAN, such as streaming music on iTunes from one computer to another. And theres things like file sharing between a Mac and a PC. Does anyone else know of any other things that you could do on a LAN. And I have two questions. 1) Is there a type of application in which you can (IM) people on your local network (besides Rendezvous-something maybe compatible with a PC)? 2) I have know problem sharing files from the PC to the Mac, but I can't figure out how to share Mac files to the PC. Thanks for any input.
