My dad has a G4 power mac and an iBook. He uses the G4 a lot at home and takes the iBook when he goes away on work. Is there any software/system where I can get the G4 to sync emails & schedules between the two? I know iSync does that but he's not prepared to pay $au200 annually for that service.
I was thinking of getting ADSL and a static IP and setting up a small win2K server with exchange and an imap service. That way he could use Entourage (which is excellent) to do this.

Does this sound reasonable?
Are there any other suggestions?
