Sorry to bump an old thread, but I've ust been speaking to Alan Chow of Chowmain.

He tells me their new Control4 Cbus driver is in Beta stage right now and from what he tells me, it should be pretty damned awesome with excellent programming capabilities.

Biggest thing of note, is the ability to program eDLT text from Composer Pro. This is huge for me, as I HATE Toolkit.

Should be live in the coming months.
