well if it doesn't have things like mirror/swap and other stuff for the ilda input, your ARE going to need another board/electronics for that. we are GOING to compare this to Moncha.net and etherdream. But i'm sure good manufacturers will have all as options you can choose from when ordering an entertainment laser.
it's like having a media server built into a projector. might be cool on something like a High End Systems DLV but who will rent that when a normal tour video projector is more desirable/ fits more markets. Not to mention more people want to hire a video projector than a laser. CITP came out of controlling media from the lighting console. Are the video guys mad? or does one become diversified in multiple aspects of live performance? it's just another tool for what is ultimately an expressive instrument meant mainly for artistic entertainment.
