anyone know if power over Ethernet is possible with the power consumption of the plug?  Any consideration on this front?

should be possible. max poe is around 12.5 watt. You would need to spilt it from ethernet, convert it to 5V and then feed plug with normal ethernet and 5V line.

POE is possible as it can draw up to 2.something amps...

If you need a POE adaptor I recommend the Cisco 5v POE unit...

PoE injectors/adaptors only give out DC. Unless you rip open the plug and tinker around so it also powers directly of DC I dont think you are going to have much luck. A PoE port would be a good addition to the plug.

Not difficult!  ( On V1.3 Sheevaplug which I have)

Open Sheeva plug case   

Unplug 5v connector  on  sheeva  SOC PCB.  (from mains PSU +5V output)

Remove Mains PSU,  (just unclip ally box), and mains figure 8 socket

Feed POE 5V from POE splitting / conditioning device, through hole where mains figure 8 socket  was removed

Connect POE 5v to Sheeva pcb, (Would  need to obtain suitable +5v connector. standard part, unless you chop the old one off the mains PSU o/p cable and join it to POE 5v)

Here  are pictures of V1.3 pcb:- http://plugcomputer.org/plugforum/index.php?topic=683.msg4148#msg4148

On last (4th) image Power connector is 4 pin top right, pins are paralleled up for current capability

Job done!
