Yes there is a standard

I would NOT do this.. (use a non standard voltage on the PoE)
too easy to hook the wrong thing up, some day.. Maybe your NTP widget is
up on the roof, and you've got a buddy helping recable with a new switch
that puts 48V on the wire, when your widget is expecting 12...

I was a little worried about the comment regarding isolation being
hard to implement. The standard for Ethernet required galvanic
isolation on all Ethernet ports by use

If you are making and selling a product you have to assume others will

I think PoE is a great thing, because it allows you to get rid of all those
wallwarts..
More importantly than simply getting rid of them is that with PoE you
can place your Ethernet device in a location where there is no place
to plug-in a wall wart.

Hi
If you go the DIY route to PoE, be careful of the converter bricks you decide
to use. Switchers by nature put hash on both the input and output terminals.
You want to avoid back feeding crud onto the cable. It's common mode, but the
chokes and transformers only isolate to a limited degree.

coaxial power input. Also this would make it real easy to place the
server right at the antenna location. You would simply run cat-5 up
