Greetings:
CURRENT SITUATION:
I have a Virtual Theater Pipe Organ running Hauptwerk which handles MIDI->virtual theater pipe organ stuff.

I also use a program called Reaper, running Hauptwerk as a VSTi, simply to add reverb as many of the virtual organs are recorded dry.

I would like to add an Electronic Organ (Lowery, Hammond, Wersi, ETC) style backup rhythm accompaniment, and it would seem BiaB is ideally suited.

QUESTIONS:
1) Currently running Win XP 32 bit and hitting a RAM limit so in the next 6 months I will be converting to Win 7, 64 bit and wondering if the licencing will allow removing BiaB from the XP and installing a 64 bit version on the Win 7 machine.

2) Can any/all of the Biab Transport functions be driven by a MIDI message? I would like to use a 2nd Novation LaunchPad device to control the BiaB transport functions to emulate the functionality of the aforementioned electronic organ rhythm features. IE: Start/Ending/stop a given rhythm track. If so I would purchase a 2nd Launchpad for just this feature as my monitor is normally displaying my electronic sheet music and I would rather not have to switch screens to start a track then switch back to start playing.

3) Can BiaB host my Hauptwerk program as a VSTi? If so, I assume BiaB can add reverb to the VSTi thereby eliminating the need for Reaper.

Thank you for taking the time to read these questions.
