Hi,...well DLP AFAIK is used to replace CRT or LCD or "classic" projectors/beamers. So it shouldn't be a problem to eCS or Snap as they have nothing to do wit it:
Some manufacturer will build a "display device" that uses DLP inside, but... that device has to be attached to something that the pictures come from... which most probably will be something using a digital signal to benefit from the DLP advantages (just like DVI connectors on graphic cards). Your TFT or CRT also has a VGA or DVI connector, right? They won't leave you standing with the panel or tube only... that's the same for the manufacturer of a - say - DLP TFT display. The manufacturer MUST provide you with a way of attaching your stuff to the display, otherwise no consumer will buy that thing. So in matters of attaching a PC to a DLP display device, there should be the least problems.
Greetings
