No. Not if I'm concerned.

But quality control, as well as working condition, is an issue that is 
difficult to check without physically being around.

The price level for the Raspberry Pi is possible because the closed, 
undocumented chip is sponsored by Broadcom, and the board is produced in 10k 
volumes (as you probably are aware).

See a previous mail from Christoph; about 500 euro per 8-layer PCB (EMTPY! No 
chip placed yet!) in small volumes. The board is close to what is technically 
possible, not counting eg aerospace (space would have a lower complexity, but 
for the sake of argument). 

One reason for the complex design of the Phoenux is minimization (case 
restrictions on the one hand, and general minimization on the other). 

The designs for the allwinner_a10 hope to use a 2-layer board, of which two 
PCMCIA-sized boards are needed (one CPU/graphics board, one periphal board 
with RF chips, USB and so on). See [1], [2] for images.

The project certainly looks interesting, but it is not yet in a state where 
GTA04 was over 2 years ago (remember that during FOSDEM 2010 there was a 
working prototype of GTA04, already further miniaturized than the design at aims for).

Of course we're on the same side: everyone on the list "desperately" wants an 
open communications device, preferably with enough toys on it to make it even 
more fun. I think the goals you set are not realistic; a sub-300€ GTA05-device 
might bear the name, but not the ideals of an Openmoko device I think.
