After a message to debian-custom from Baruch Even I decided to apply as a mentor for Debian on Google's Summer of Code.
If someone is interested on working on the current CDDT code or even on a project related to the development of Custom Debian Distributions (or even derived distributions) I'll be happy to mentor you if your write a good proposal.
I'm not doing much for Debian lately, I'm busy at work and mentoring someone looks like a good way of helping a little; it requires less time than doing things myself and can be a good way of taking breaks of my real life duties during the summer, when I'm supposed to be working on my PhD Thesis.
