Connect One Ethernet shield

What about jumpers? Add a little to the cost but it might be worth it in the long run.

or how about solder jumpers? No added cost at all..

I've done a bit of both and also added through-hole pads to each of the five interface lines so they can be rerouted by cutting traces and adding wires.

One remaining issue - the socket for the mini iWiFi is taller than those for the other two modules.It's not a problem for end users but is for testing. I guess I'll have to find people with each who are willing to test and maybe write a short tutorial in exchange for one of the prototype boards.
