Heard about this a few days ago, awesome that it's getting publicity like this on MacBytes...from what I know, there are only a few devs right now.
Best of luck to the project, it sounds really promising. I downloaded a copy, ran it in X11, was able to open the (included) Windows program Notepad, save a little document...it was kind of neat. Way faster than VPC (I know this from that experience and from asking someone in the #darwine chat room on irc.freenode.net).
