Synchronization to multiple workstations.

[slither]

Would it be save if to use a USB hard drive or network folder to synchronize files between multiple workstations? For example if I make changes on PC1 and synchronize with the USB hard drive, would I be able to get my files synchronized on PC2 by doing a synchronization between the USB hard drive and PC2? Obviously I would not expect ViceVersa to resolve conflicts such as the same file being updated on several PC's but would it flag such conflicts? What would happen if jobs were running on a schedule instead of manually and two or more PCs would start simultaneously jobs to synchronize from a network folder at the same time?
