Fabian is a NYC based Swiss wanna-be-entrepreneur who spends all his time trying to make meaningful connections between ourselves and business.(and I chose charitably) but not anyone whose potted bio mentions being an RF engineer.
Actually, I think that it would be more worthwhile to start off with the low-cost open source satellite radio, as this may be the difficult bit and would be highly reuseable in other projects. A lot of Indian or African GSM people would find a cheap satellite radio very useful for their backhaul requirements. Depending on the spec it could be used with things like the amateur radio AMSATs, the transponders on the ISS, and the spare US Navy FLTSATCOMs. USRP is way too expensive at the moment (they cost more than a cheap netbook) so that one's out.
