Congrats on having the fortitude to make it though showexp_list;
some grungy code in there.

My recollection of what I did is that you create a project and users
that join that project can see the entire experiment list. You want to
give everyone "user" privs in that project when you approve them.

Note that the mechanism assumed people play nicely. If these are
students working on a class assignment, then we want to be sure there
are no holes that would enable them to get root on experimental node
and then dig through the homedir of another user. "user" privs will
prevent them from swapping in an experiment in the holding project.
But still want to be careful; I never thought through the full
implications since it was not too much of a concern here.

Thanks, will fix this.
