Possibly, slightly off-topic: Current makes of the iBox2 wifi controller support an 8-channel remote which I am currently integrating.
I am not yet sure whether or not it is tied to the iBox2 controller per se or it is matter of firmware version installed on the ibox controller. My wild guess is the latter applies and thus newer makes of the ibox1 controller might work as well. Mine does not work (possible because it does not has the right firmware version). Unfortunately, the vendor does not seem to support firmware updates.
Another curiosity is the 8-channel remote uses an unique command set even though the commands seem to be same as the 4-channel remote for full-color.
