If you can't administrate the machine (i.e., add groups, add users to
groups), then it's going to be /really/ difficult. I'm mentally throwing
my hands up in the air and muttering something about "not really a group
then, is it" :). I find it a fun exercise to think of a permission
system that will allow a reasonable granularity of access permissions,
but not being allowed to add groups seems like an unreasonable
requirement. I'm out of ideas.

You need the CAP_CHOWN capability, which normally only root has. I'm not
acquainted with changing capabilities; I have never done it.
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
