i ran into this  problem as well with my project, thats why ive been asking
around for hirose 60 and 92 pin jumper cables. if we could track down
someone who makes those, then you wouldnt have to physically sandwich them
together. i think this would be awesome because it would make the gumstix
platform more flexible in terms of putting it into an enclosure. for
instance, instead of making a small, cell-phone like enclosure like they
sell on the website, you could use something with a bigger diameter but
extremely thin. it might be useful for many purposes.
unfortunately, i still havent found these, but i will let you know if i do.
(please do the same if you find a solution.)
