    Splitting the signal from a DAC is easy, in fact, the breakout board I use to sell had a passthru option, which essential was a splitter to feed a 2nd projector. The only problem is with input impedances of some scanners/laser drivers vary wildly and can cause issues. The best route I found was to send the ILDA signal to several buffer/drivers. This way each projectors is somewhat isolated from the other.

    You should post it anyway, I'd be interested in seeing it.

    Are you refering to the pic I posted? If so, that wiring nightmare is on the front of the box, which is nothing more than a bunch of lighted push buttons to individually turn on R, G or B on each projector. There is also a switch to change the input from the ILDA port to an internal quadrature square wave oscillator for setting up the projectors. The individual DB-25's are on the back side of the box, just out of view at the bottom of the frame.
