Hi, after some interesting times I got this up and running, but there is
some problem with the IDE, after I updated compiler to 2013 version, I got
rid of the c++11 flag error, now it is missing path to include the
inc-directory where system_init.h file is... I could not figure out where
on platform.txt the include path information is set up!?

But the make file based environment works like charm (after I corrected a
naming typo and because there are more references to spiAPI.h...):

libraries/SPI/SPIClass.h:#include <spiApi.h>
libraries/SPI/SPIClass.h:#include <spiAPI.h>

this is tcpdump from (firefox)copper-dialog:
