The demo consists of :
 - A new DSP patch
 - A new ARM firmware for the phone
 - A complete replacement tranceiver app for OpenBTS

You won't find any of theses anywhere yet, so you can stop looking for
now. But hopefully you should get some news at 29c3 :p

The osmo-bts code is now geared towards sysmobts hardware, hopefully
it should be used in the final version but for now it was easier to
reuse openbts as-is.

Cheers,
