Openmoko Beagle Hybrid

Yes,
this all can be considered for a future version.
What we wanted to start with is something that just works, is easily 
available, can be used for experimenting and software development and 
is not too costly. A nice case, a new PCB for the OMAP processor or 
using the Gumstix makes things much more expensive.
@Yocto: what has to be considered is that the Gumstix does not fit 
into a Freerunner case (it is still too large/thick).
@ Martijn: the OMAP BGA poses high level requirements for a new PCB. 
So I would be surprised if one can really get such PCBs for 15 € @ 50 
units. But do you have more information? What have been your 
assumptions about # of layers, min. drill size, min. width etc.?
