I’ve decided after all that we’ll stick with KISS for the next set of
Rybka releases.

Rybka 4 will be released and sold when she is ready. Detailed
information will be available at that time.

Remote Rybka hosting will begin when that is ready. Further
information will be available at that time. We’ll follow some sort of
soft launch protocol.

I’d like to apologize to the guys at Convekta for changing my mind
about several major things at the last minute, and to wish them luck
with their upcoming Aquarium release.
