This is more or less the solution I tried. However, when a user creates 
a file on this system, the permissions are (for example) paulf:paulf. 
This means that, despite the directory permissions, other users won't be 
able to modify the file normally (assuming a system umask of 022).

However, I did just read an excellent explanation of the setgid bit, 
which apparently, sets the GID of a created file to that of the 
directory, rather than the file's creator. This might work. I haven't 
tested it yet.

I've heard of ACLs, but never had the need to user or learn about this. 
I'm assuming that attending to ACL issues requires additional steps in 
the creation/editing/deletion of files?
