Graynomad:
I would also vote for a format that doesn't use 100% of the edge real estate for the backplane, there's hardly anywhere to put your own connectors.
@Graynomad:
What do you mean by "100% of the edge for the backplane" -- the double-row header socket at the right edge? But if so, isn't that part of the standard Mega format -- and thus all corresponding shields, for those who want to use them?
