From what I've read on the Pyra forums, I'm sure there would be some interest.

(I also wonder what the interest would be for an open version of the GCW-Zero, 
given that Michael/EvilDragon has expressed dismay over the availability and 
quality of that product and yet has no difficulty selling them when they 
occasionally pass through his shop. But perhaps he should take it easy for a 
while before considering new projects!)

That is too bad as far as you being able to offer a product of this kind, yet 
it then makes me wonder whether the PocketBeagle might be able to act as the 
basis of other products. Or maybe this would be too much like "bricolage" as 
Sven called it.

Although I do support EOMA68, I can see that some of the choices are 

It is interesting to see that Olimex have made a proprietary "SOM204" 
interface (3 * 68 = 204, coincidentally) with lots of signals to cover lots of 
applications, but this might be sacrificing the accessibility of the 
technology for flexibility. In other words, it may not be a problem for Olimex 
to put out new SOM boards, but perhaps the complexity might be too great for 
people wanting to make their own boards or the carrier boards that would 
accept the modules. Maybe that is the point of the exercise, however.

Agreed. The big change was that such boards became cheap, perhaps by 
pretending that they could be used by a wider audience, instead of remaining 
niche items costing hundreds of dollars.
