That's assuming that the remote ports provide PoE. But even if they didn't,
a non-PoE port requires some power to do it's thing and the power you get
from upstream just isn't enough for more than a couple of non-PoE ports.

I did find out that NetGear has a 5 port PoE powered switch, but I find it
hard to imagine a scenario where that would really be useful.
