Google soc 2010 ideas

Hi, people. I am a PHP developer for 5 years already. I am mostly interested in MVC frameworks and ORM/XML binding model development. I am searching for a mentor to apply to Google soc 2010. My main topics of discuss are: 1. XML binding library, similar to ORM, but for XML models, with a possible facility of translating PHP reflection driven manipulation to appropriate Xpath expressions, for using in model layer of MVC based frameworks 2. A library for mapping complex regular expressions(Posix) to PHP 5 OO classes, where expression nesting would reflect persistence issues, representing both entity association and/or aggregation where needed Please share your vision about all this. How actual is those stuff? John Thanks for anyone for helping. John
