Automatic Bitcoin Distribution system

I was wondering if there was a project anywhere that performed automatic Bitcoin distribution.

Here's the problem I'm trying to solve. I have a mining system that earns N number of BTC every day. When the pool sends money to a given address, I want an app that will read from a config file to determine how to break the BTC received up into smaller payments, then send them.

Let's say TargetA is the address that the pool sends BTC to every time the balance reaches 0.5 BTC in the pool.

Then using cron I run an app that checks TargetA to see if there is a balance.

if not then it dies

If so then it reads the config file and sends the BTC
TargetB 50%
TargetC 25%
TargetD 10%
TargetE 15%

This seems too simple to think it's not been done before.

Before set the course to write one I wanted to first check to see if there was one. I'm not even sure what one would call such a system. I've tried google various terms, looked through the wiki, looked through BitGit. So I thought I'd try this.

Thanks in advance.
