Power over Ethernet for Lighting - LEDs

Have ongoing work interest in 802.3af and 802.3at Power over Ethernet
http://en.wikipedia.org/wiki/Power_over_Ethernet
for non-classical applications (not VOIP – voice, video). Mostly interested in sensors, actuators and protocol/serial conversions via 802.3af. Communications drives these applications.

What if we drove further and looked at how far 10W could get one in a real physical application with an eye to communications. Lock strikes, dampers, valves, keypads and small displays get into this realm. What if the deliverable was literally power? What could be useful at 10W? The answer is that LED lighting technology is now practical at this level.

Scenario for LED lighting:
-Space (house/suite) wired for Cat5e or Cat6. (as-built or retrofit).
-802.3af managed gigabit switches installed (for use with VOIP as starter) like Dlink DGS-1210-10P.
-Unused sockets get 802.3af LED lamps (prototype – Trendnet TPE-112GS – with a 5W USB desk lamp).
-Local and (intelligent switch) managed control of the LED lights.
-UPS backup of 802.3af injection, and thus lights, where needed.

This involves only safe low voltage wiring. International acceptance/use/deploy possible.

Build 5-10W LED lamp with RJ45 connector and module like Silvertel Ag9600/Ag9700 series or similar (Ag9605? Ag9603?). Interesting if one could get 802.3af direct to LED driver (current) circuit.
