The sample php code is supposed to be used either internally amongst a
closed and trust group of users (perhaps behind a .htaccess or on a
private network for sysadmins) We were hoping that others would take
it as a base and improve on the first implementation.

But yes I do agree that more work could be done with filtering the
input and not trust the user to put the correct thing in.

Perhaps Peter could shed some light on this issue.

This done in this way so that we would have the possibility of not
passing too much data to the client.

We could re-implement some of the front facing php code to not use
jquery, patches are welcome :)

Excellent, slurm is a great resource manager, we've been using it for
a few years now after migrating from torque/pbs. Also if you don't
mind would if i forward these few emails to the slurm-devel list?
Could we keep the discussion on the slurm-devel list?

Thanks,
Jimmy.
