3 port inline PoE bridge.

[rebelwireless]

I've been looking for a solution for this, even working around it in less than optimal ways. If you guys could build this inexpensively I think it would be a hit.

So, two input ports. both should ideally take PoE input. Maybe 802.11af/at or Passive. One 'output' port supplies PoE.

A switch chip capable of large MTU and QinQ in the middle.

what this enables is a very simple physical layout allowing for rendundant switches and routers. Then, your router of choice can do VRRP, CARP, or whatever flavor of redundancy you like.

for an example of a workaround, see Jim's setup here:

This is basically using ER-POE units in place of the device I describe. To work around having only single ethernet ports on almost every radio commonly used by wISPs.

I think that the device should be extremely simple, 2 ports on one side, 1 on the other. No buttons or anything except a power led probably.
