POE networking, what's the range?

[Michael Johnson]

This isn't really a FreeBSD-specific question but does
anyone know the range of Power Over Ethernet? I want
something to go from my house to my garage apartment
then hook a wireless access point in to the POE box. The
garage and the house are on their own power circuit but
where the lines split is in between the house and the garage.
I'm thinking it'll be around 600ft plus all the wiring in the house
and garage. I'm kinda hesitant to buy one and try it before
I *think* it may work.
