New Product Ideas / Stackable CPU boards

(continuing from the comments)
Sharing signals shouldn't be a problem - it's just a matter of defining which CPU controls what line (and when) and putting all others in some high-Z state. But it would be more useful just to share power and a communication channel like I2C, and connect all other pins just to one side, e.g. the upper connector. If space allows, connection to the lower connector could be through solder bridges.
