I made this =)
You may have participated in similar projects I've done before:
The service makes use of PHP/PostgreSQL in order to fulfill it's duties. If there is sufficient interest in the source code I may release it with a free license. Just a heads up, I do not think I have made use of any 3rd party libraries. I've probably reinvented the wheel many times. The term Not-invented-here-syndrome may be applied here. I have not done this because my way of doing things are better, or because others have not done it right. It is just for the pure pleasure of developing and learning.
