another idea to solve all problems with the snapserver (not tried and only theoretical) and
only a short and dirty explanation of my thinking:

what about this way:

- create only one big share at the snapserver and get sure you are able to use the share from windows
- load and install truecrypt from TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows XP/2000 and Linux
- open truecrypt and format the drive (the share from the snap) with ntfs

after waiting some cups of coffee it should be ready to use, reboot snap, reboot windows and start truecrypt. after that try to mount the share.
now there should be a network share with ntfs

if this operation fails, you can format the drives using the snapos...

at the moment there is no truecrypt version for vista, but if it will be available, I'll test this at my own snap.

I repeat: only a theory, don't know, if it works or will kill the snap, you should make a backup-image of your snapos (like mentioned at wiki.procooling.com).

If somebody would try this before myself, would be happy about a short information, if it works...
