uaEFI carrier board interconnect

[dare951]

I'm thinking about designing a carrier board for an uaEFI and I'm wondering what the preferred method is for the board-to-board interconnect. Ideally I would like some sort of detachable connector, like an IDC header or such, at least during prototyping. I've done some searching but haven't found a clear answer to what people are using for this.

I do see that the uaEFI PCB has .1" pads in sets of 4 for some of the connections, but not all. Is there a reason some signals weren't included?

Thanks.
