In the days of Windows Sync Center, it was possible to associate a device with at least 2 PCs, because I guess people would plug them in at work and home.
With Zune, I can create a Sync relationship between my device and 1 computer, and then connect as a "Guest" device on other machines.
Is it possible to create a Sync relationship on both my work and home machines? If I change the relationship at work from "Guest", will that break the relationship with my home PC?
