Interesting topic!
The starting point is that Soundflower does its jobs. This should be the setting:

1) on Biab: do nothin
2) on Mac preference panel, set Soundflower 2ch as sound output
3) on Mainstage, preferences, set Soundflower as input source, and create an audio channel strip where the I/O assignment is set to "input 1-2".

The flaw in this setting is imho that you need to go to biab to start the song, you can't do it from mainstage.

It would be interesting to have other opinions about this subject thought...
