Just saw Josef Prusa's video on his new i3-MK2. Two big improvements that I see are the new print bed and the integrated Z lead screws (scrapping couplings altogether).

I'm thinking that if the i3-MK2 improvements were merged with the Foldarap, you could change print height/volume by replacing the Z extrusions and Z screws (search Thomson Taper-Lock for a video of replaceable lead screws on their stepper motors.
with the Foldarap frame and the Prusa i3-MK2 merged, I think we may have portable 3D printing gold...
I'm just "spit-balling" here, and see what sticks... ;-)
