Development talk happens in #linuxmce-devel on irc.freenode.net. To start, you can read "developing a dce device" on wiki.linuxmce.org
In addition, you can also read the page titled Developers Guide, which gives a comprehensive conceptual overview of the entire architecture, and you can talk to us on IRC.
If you're willing to put in the time to try, we all will bend over backwards to try and help.
