Proposal - OJB port for PHP

Hello, This semester I worked on a big project using OJB (http://db.apache.org/ojb) as a data abstraction and persistence layer, and after the "thing" started working, I realized the power and simpleness of OJB and how good it would be if it was ported for PHP. Based on this idea I went on writing a simple example has how I would like someone to use my port of this ORM tool. Attached with this e-mail goes the example code. Take a look and give me your feedback if it's a good idea that I should work on, and that can possibly be useful enough to add to PEAR. Otherwise please direct me to the packages that you think that already fill my proposal objectives. Regards, João Cruz Morais
