For what I saw, the circuitry is not opened, or is it? I fear that, unfortunately, I didn't see it anywhere so it seems they haven't done that, although they are surely willing to disseminate the usage of technology.

No the Pi is not open.  The licensing agreement with Broadcomm is one of the major liabilities with the Pi.

The Beagle/Panda/etc use TI parts and they are more friendly to open hardware (although you may have to buy TI's dev tools to get the most out of the hardware).
