Ok, I'm beginning to understand. Sorry to imply I was looking for a step-by-step (well, I'll take it if it's available!). I'm willing to learn and apply, though.
I did some more searching and found this thread again: which to me implies that I would be connecting the Midi Thru from the BCF to the Midi In on the midibox LC.
To answer your last question, the BCF2000 receives the Mackie Control stream directly from the DAW. BCFView is not required at all, it's just an emulation of the original MCU LCD's. In fact, in the BCFView application, you need to select the Midi device for the application to receive it's data from (i.e., the BCF2000), so the idea of connecting the midibox via the thru port of the BCF2000 seems to make sense.
It looks like I'd have about $50US invested in this. If it works, I think it would be worth it. It would still be nice to see someone's completed version of this, though. It appears there are lots of people who have had this idea, but all the threads discussing it end with no confirmation that it actually HAS been done.
