OP wants to design and build his own radios using USB wireless dongles and Blackberry Pi motherboard, and set a mesh network where all the dongles communicate with each other.
i like the way you said that, made me realise how hilarious my ambitions are....
I'm just really trying to understand the internal logic and capabilities behind these devices, and pick and prod to try and come up with sexy shiny ideas that lead to heated discussion and hopefully development.
When I think about stuff, my logic goes : "Why does this work, why can't we do this, how can this go....."
