Help with Hyperpin/spin/mame/visual pinball multiscreen problem

[gwjrabbit]

I've posted on the hyperspin/vpforum and had no response, but this place feels like home, so I'll try here as well.

I'm building a combination pinball/mame cab.  The Mame cab is done. It's awesome. Your basic modular-panel, 32 inch widescreen jobber.  I now want to build a pinball playfield that rolls in front of it (I have a 40 inch LCD already for it).  In Pinball configuration, I want to run hyperpin and visual pinball.  In mame configuration, I want to roll the playfield to the side, and just have the mame screen.

The problem is, this means I need MAME and Hyperspin on the cabinet monitor as primary, but in pinball configuration, I need the playfield to be primary.

I know how to make MAME default to different monitors, but hyperspin and pin both want to be on the primary monitor no matter what, and visual pinball seems to always want to put the playfield on the primary monitor.

At the moment, as far as I can work out, my only real option is to abandon hyperspin for mame in favor of something that explicitly lets me run on secondary monitor.  But I'm hopeful someone knows some windows 7/autohotkey/necronomicon magic that might solve my dilemma for me. 

The fixed points here are mostly financial: I want to use the same computer, and I want to use the MAME monitor as the backglass for the pinball configuration.

Any general thoughts I'd really appreciate.
