Probably a diode or two in the box.  I had to add two diodes to my Ricoh
P&S twin rig to eliminate camera firing when turning them on and off.
My Canon SLR twin rig also suffers from crosstalk when the metering
circuit is energized.

You can have both worlds with your twin SLR setup.  Just make a hinged
twin bar like I have on my web site.  You can instantly switch between
hyper horiz. and near normal stereo base vertical formats.  In addition,
full frame vertical format slides are a nice change from horiz.
compositions.
