If it is really enough space to be worth the trouble, there are an
assortment of unionfs versions for Linux where you overlay a writable
file system on top of a read-only copy and it does a copy-on-write of
anything that is changed: http://en.wikipedia.org/wiki/UnionFS. With
this approach you could check out one copy, then overlay COW filesytems
for each user - and share them out with samba for the windows users.
The down side would be that it becomes less efficient as changes
accumulate and you'd have to blow the whole thing away and start over if
you update the underlying master.
