Oh My! With a negative power feeding to the LED's via the host, one could use DTP with emitters that don't have dedicated thermal pads. This light's design will open up some nice possibilities. :)
EDIT: Haven't decided if I will join this GB due to the clear finish, but I certainly wish the best on the endeavor. Very sweet light this will be for sure.
NarsilM is com'n along pretty good now. 2 and 3 output channels can be configured with compile time settings. Been testing it on a triple channel board.
Think'n it would be perfect for this light - same UI, same manual as for the BLF Q8, and should also work for the BLF GT.
