Ok so far I've discovered the "gpasswd" command which allows me to set a
password for the group and apparently apoint an administrator of the
group though my idea is to have the user su to the matlab user then
newgrp back to their own group (each user being in a group of one). So
perhaps I can appoint the user as the administrator of their own group
of one at account creation time.
So I login as peter, su matlab (without the '-' which means I stay in my
directory though my uid/gid is now matlab,matlab) I then $ newgrp peter,
which prompts me for the group password and I'm now still in my home
with uid=matlab, gid=peter. I now run matlab able to read/write files in
my own account . When matlab finishes I need to undo the newgrp and su
commands I just need it all wrapped up in a script, hmmm.........

Use sudo rather than su, and use a wrapper to provide exclusivity.

Ok, I think I follow, sudo can run a command as another user, cool, That
command needs to be newgrp, then matlab, then exit newgrp. Another dragon?
I'll follow that line for a bit I thinks
