Bc2000 (for the BCF2000 & BCR2000)

Has anyone been able to get more than one BCF2000 to work with 
Tracktion2 host DAW, while maintaining bi-directional support?

i'm able to get one or the other working, but haven't figured out how 
to get Tracktion2 to allow the 2nd one to work simultaneously. Ideally, 
they'd function within the host as a single control surface, 
controlling 16 tracks for each preset... am i just dreaming, or is it 
possible? i've talked to a Behringer rep, who personally had 2 working 
with another host program like that, and he said that he thought it'd 
be possible, as long as Tracktion supported MCU emulation, which it 
does. Behringer isn't exactly setting the standards for support, so if 
any of you are able to help me, i'd sure appreciate it!
