This is my first post so be gentle

What i want to achieve is something like codepad/ideone to run an online open source community, a lot is already programmed but i just want to include this functionality.

I want users to post sourcecode, run it through the correct compiler/interpreter, add the STDIN with the script, compile, run, and then show the response.
Of course, there's some theoretical problems but all sites solve this with constraings:
For example:
Compilation time is very limited, from 5 to 15 seconds.
Program size is limited to 32-64kb
Running time is limited to 20 seconds.
ETC

Also they can only read from STDIN and write to STDOUT. In my case database fields.

How can i set up a sandbox environment or some sort of slave compiler to to do this stuff?

I'm managing everything with perl and a mysql database, and possibly (like you could live without those) shell scripts.

Thanks in advance.

What you could do, and I would strongly suggest you run it on a host that only has a LAN connection, is to confine the process to a virtualization guest. QEmu, VMware and other virtualization software allow you to start, suspend, stop, resume and snapshot virtualization guests so they will be accessible in near real time, stopped after a period of time and their contents can be reverted without more than a single command.
