There are such solutions, but why bother?

A simple linux set up with remote ssh is enough.
Everyone gets a home directory, nobody can sniff what others are doing
(and there is no time). If you want more, namespace separation (to
disallow people spoofing the options used for grep) or LXC is in
order.

Tasks are given by copying a certain directory, submitted by producing
a file in ~/answer.txt ( a loop watches all ~/answer and greps for the
right answer).
Alternatively setup a git repo, clone in a new branch, commit/push
back, add a server hook to look for correct answer and play a
"BANG.wav". (branch is needed to prevent people from having unresolved
conflicts).

Cheers,
Kalin.
