Starting a Cpanel-like Project for Ubuntu Server

I need your advice on how to start a F/OSS project. Where's the best online hangout to gather devs for this? Where's the best place to put the code as we build it?

I'd like to invite PHP developers (who know a slight bit of Kohana and Bash) to help me build a Cpanel-like F/OSS package for Ubuntu Server. Sure, there are other packages out there, but none equal the simplicity and intuitiveness of Cpanel, and also I want this to be GPLv3.

The first goal will be application security because panels like these are often targeted. Following that, I wish to start on the login and the main page, and make it work in a shared hosting environment among many customers. From there I want to build an easily extended API where one can define panel sections, and then panel icons in each section. At that point, the team splits up and starts focusing on each icon-connected script that does a specific task in an intuitive way.

If you have advice on starting a project like this, let me know here.

If you are interested in joining me to build this, then contact me with either a message reply or PM here:
