Theres a few of coders around the network.
Ghostship is coordinating the main effort with a coder.
Zhen Logic, Zenar, Richy and Eagle have provided some assistance to varying degrees along the way.
There's other C coders in the community and many coders of other languages. To my knowledge there are no other projects to work on a patch. There was some mention a while back that Pri was working on something but I haven't heard anything of that for a while now.
