whatever happened to this?

i support the CAN idea.

It's not TOO expensive... maybe just some additional chips per board, depending on the microcontroller you use, you may be able to find one that has CAN integrated into it.

I prefer the I²C method

As for connectors couldn't we use a 4way molex connector http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=4838483 These are one way aren't they? (I know you can force them on the wrong way but why would anyone do that?) I Know they limit the stackabilty of the boards so may be out.

Hole spacing: I'd like to propose two mounting holes, one top left and the other bottom right, relative to the I²C bus connector. The holes could be centered 3mm in from each edge.

Those connectors are OK because thay have the same pin spacing and size so you can still use regular female connectors for the stack up boards.
