I would think the best way to do it is to have a group 'share' and set
setgid on the shared directory to 'share'. This way, we can keep track
of which user created what.

Now, if the user wants the other to be allowed to modify the file,
it's just a matter of setting the group-writeable bit. Examples:
- shared dir:
drw-r-s--t 0 root shared 0 2006-06-10 10:00 /home/share
- newly created file:
-rw-r----- 1 ryan shared 0 2006-06-15 20:30 testfile
- writeable shared file
-rw-rw---- 1 ryan shared 0 2006-06-15 20:30 testfile

Note that it would be nice NOT to have the dir/file world-readable.
