You can now anonymously sync. to the bleeding edge version of Kodachi’s source code at svn://nextbbs.com/kodachi
If you do not feel like installing svn/compiling Kodachi but are still curious about its source code, you can browse it at http://www.nextbbs.com/trac/kodachi/
Note : if you sync. to the first check-in, you will get the version of Kodachi that is currently downloadable. If you sync. to the next one, you will get a new version with a temporary default interface. Yes, I am working on adding customizable interfaces.
