What would be the chances of being able to get a second ethernet port integrated into a PIXADx ? I have no idea what the innerds of a basic ethernet hub was, but if it was basic - perhaps this would allow daisy-chaining of controllers, rather than running back to base?
Also, given a lot of situations require the controller being placed close to the pixels, there's probably times when only a single output is required (ie PIXAD1) Would this simplify a PIXAD4 at all, or not really make any difference?
