The users of the network have a personal share in an smb share, lets call it \\FILESERVER\USERS\%USERNAME% which in windows is mounted as the personal home drive (P:) and the documents folder redirects to that drive, this drive is also made available offline with windows CSC.

Unison has this folder marked as removable. This way I use my documents folder and it doesn't matter if I logged in being connected to my work's network or not and when I am connected to the network I use unison to sync the local copy of my Documents folder with my remote folder.

This setup doesn't cover the shared profile requirement but I guess that with some tweaking it could be used to achieve something like that.

Hi Dave,
Thanks for you input. I will have a look at it and report back.
Best regards,
