@Javi: If you need only a bunch of them, why would you want to manufacture your own PCBs?
In fact Duane spotted something (a selling point) that I'd missed -- I thought that our proto-shields might be useful in an educational role because they woudl allow multiple students to share one Arduino.
Duane noted that he often has multiple projects on the go, and that it's a pain swapping things in and out, to the extent that in the past he's bought additional Arduinos (as have I), and that it would be easier to build different projects on different proto-shields and then just swap them in and out on the Arduino...
