At the moment there are unfortunately only maybe 12 people whom contribute code into ZM. A majority of those are just simple bash scripts. There are 4 of us whom really collaborate to any degree. Phillip Coombes the creator does most of the the coding for ZM, while Ross Melin and my self do simple bug fixes, compile packages, and maintain our Distro's.
ZM runs great on Debian but like I said it will take a bit for me to adjust to deb since we have been on RH.
I have a core setup now and will be working to get something setup for a media center shortly (could use any good pointer anyone has at this point, just PM me with those so we are not cluttering the posts with off topic stuff). Once I get comfortable with deb and how Pluto does things I'll hopefully be able to contribute.
