batch will sort of sort it out; it will run more depending on
loadaverage.

I wrote a couple of modest Perl scripts to handle this kind of problem.
In my case, I wanted to stage downloads so as to not thrash my modem too
hard.
You might also equip everyone with their own quad Xeon running Linux,
Hercules and Linux/390.
Then defy them to get in each others' way;-)
I don't think the idea's too silly. They could mount their Hercules
filesystems from your mainframe using NFS, and their personal systems
would just be cloned. Keep the valuables on the mainframe, don't backup
the toys.
Source code management - cvs seems fairly popular.
