pibuz the way we solved our issue is syncing our workfolder on local hard drives. Instead of syncing to user specific folders, we justed a fixed path (ex. c:\CompanyName\ )
All our common resources are located in this folder and subfolders. We use QNAP NAS for storage, and are using qsync to sync it to the local folder. However this should be possible to do with other sync software as well.
Symlinks should be possible to use as well, however it might be a bit messy to maintain.
