Yep, the other day, Kobo II was approved and went live on Indievania, starting with Tech Preview 3 for Windows. Buying it from there gives you a full version download link - no license files or keys needed! It is also possible to name your own price, should you think the current $3 is too low. ;-)
Proper Linux 32 and 64 bit builds will be made available as I get build systems in order. Meanwhile, there is an experimental Linux64 binary (from my development system) available from the official site, along with the engine source code, which is now Free/Open Source software. (GNU LGPL and zlib licenses.)
