The source code for Guncho is now available through Bitbucket. I've added a cursory roadmap to the developer wiki.
My first priority is to make Guncho more stable and scalable: crash less often, save data more reliably, handle realm failures more gracefully, run multiple instances of realms. After that, I hope to modularize a few subsystems to allow for new languages, new virtual machines, and new communication layers (e.g. a web service API).
I have a dream that Guncho will someday be able to "host" the IF Comp, with a dev environment for authors, a play environment with logging and access control for beta testers, and a voting/game-selecting/MPIF-matchmaking system for judges.
