Actually, the way I see the industry going is more toward lower power PoE. The government is investing heavily in "green" technologies that reduce power consumption, especially when it comes to IT equipment. As mobile computing platform become more powerful while still using little energy, I think you'll see computers based on mobile platforms...such as Apple switching to the A series processors in their MacBook Air (which has been on their roadmap for a while, among other things. Intel has their Bay Trail processor, which is essentially an Atom CPU that burns only about 2W of electricity, but can still crank out a pretty good workload. You also have projects like the Raspberry Pi and the Parallella (dual core ARM with 16 or 64 core epiphany co-processor) that run on only 5W a piece, but still churn out nearly 100 Gflops of compute power. If we can make lower power IP cameras, IP phones, WAPs, etc., then we can reduce our power requirements at the switch.
