Cas and RJ Please correct me if I am wrong. But doesn't dmx only have to give out change commands, the dongle just keeps giving out the same signal until a change for that channel occurs.
So once a light is set to turn green, it no longer needs a command until it needs to change to blue. Then The green will be turned off and the blue turned on.
If this is correct, and pixel net building on top of dmx, stile keeps this feature then net work load will most of the time be allot less.
Now granted I could be wrong on all this, Matt did all the protocol coding on xlights, since it is something I have never done before, but I did research dmx protocols and I believe what I said above is correct.
Edit:
BTW lor now supports 16 networks giving 65280 channels, if they can manage I am sure we can too
