Compact sACN source?

As I was traipsing around a site a couple weeks ago, hauling my laptop all over the place, running SACNView as a source to test more than 700 circuits, I thought to myself, "wouldn't it be great if there was something small and compact that spit out and read sACN data on the network?"  (no console, no DMX inputs, 45 net taps)

So my question, fellow technicians, is:  has anyone found a compact tool that will both read and spit out sACN data?  Similar to a DMXter or Gizmo, but for sACN?  Of course POE powered would be great, but a self contained battery would be fine as well.

If not, can someone please develop one?
