My intent this year (little or no Pixelnet and SS use) is to use the EtherDongle, flashed for DMX, then using the Combiner board (in reverse) to give me 4 DMX universes. Getting 32 DMX universes!!! out of a single Dongle would be great, though.
A single Ethernet cable out the window to an EtD on my front porch would sure beat 4 cables from 4 dongles.
