It would be unbelievably cool to be able to walk into an office with a laptop, and only have to roll out a USB cable from the desk in order to charge it. If there was some way of combining this with an ethernet port, all my prayers would be answered!

It's compatible with normal USB2.0 and 3.0. No reason it couldn't be offering ethernet as well as power. At that point it does indeed sound quite compelling.

I have done research on this topic, it is a standard, not ratisfied yet, and no way your old usb cables can take 100watt power(voltage/amperage), also wall sockets need standards, which is not there yet.

there are other working powered USB implementations available http://en.wikipedia.org/wiki/Powered_USB

That is the basic idea behind docking stations

20v@5a! Nice! I can't wait to see USB ports instead of the 13.8v ports we currently have in cars. Sadly my 170w laptop still would need a separate adapter.

Unless your laptop is using 170W all the time, you could still charge it using just 100W. Even a very high powered laptop is probably using <10W in idle.
