 the osmocon stuff is fully GPL'd - it's mostly written, i believe, by
harald welte.  gnuradio is entirely GPL'd.  from what i gather of that
wiki page, the rtl-sdr code *is* the driver, and it supports the
RTL2832U which is on that ebay page.

 so about the only thing, alexandru, that *might* be needed, would be
to optimise the rtl-sdr code (or gnuradio) to use NEON.  or perhaps if
you don't want to get involved in doing that consider compiling
everything through llvm or some other compiler which has automatic
NEON optimisation built-in.
