a lightning technician told me last week that dmx will fade anytime 
soon anyway, the new standard seems to be artnet, a ethernet kind of

although it says in this document that artnet will NOT replace DMX:

would't it be much easier to output ArtNet though the ethernet port 
directly instead of using those USB to DMX controllers?
