Not to hijack, but is there any setting on the Macs (I have an intel iMac and a g4 ibook) that allow one Mac to access the other even if nobody is logged onto the other? In Windows, you could always map a drive on another network computer regardless of whether anyone was logged on. It appears that with Macs, the target computer needs to have somebody logged on to allow another network computer to map the target's drive. For my home network, this is a pain because generally I'm at the iBook and need something on the iMac, but nobody is logged on there (or vice versa).
