How about routing the light through fiber optic cable?
Use one fiber for groups of VCRs, score/scratch the side of the cable where you
want the light to come out.
Perhaps drive each 'light pipe' with an IR repeater to get enough level in or
maybe even just the output of the remote jammed up close would couple enough
Shroud each input to make them selective. The remote up close selects only one,
but move it back to select adjacent groups...
Something like that....... At least then you have control over the physical
placement of the inputs.. i.e. they can be away from the front of the VCRs so as
not to interfere. The sensors could even be covered with the fiber running under
so nothing gets in from the front.. Black electrical/insulation tape comes to mind.
Just a thought, I hope I explained it clear enough.... :-)
