Yeah, that's why I thought I'd throw it out to be considered, but it's
not a super high priority.  If you do manage to offer it, though, I
would definitely advocate having no fewer than 50 accessible I/Os,
even if high-density or metric connectors are used.  50 seems to be
the magic number for implementing minimal but usable backplane buses
(Zorro-III, PCI, and 16/32-bit Wishbone all seems to fall under the 50
pin threshold).
