We see this from different points of view. :) We're interested to show possible
ways of OpenBTS interoperability with more conventional BTSes like ones
OpenBSC use and evaluate problems which will arise there. But we want to
show this with "flat IP" network instead of burdening OpenBTS with
A-bis interface.
I believe in the positive impact of OpenBTS and OpenBSC interoperability for
the both communities and as encouraging factor for possible future OpenBTS
test sites.

We're ready to work with you beforehand to minimize on-site efforts.

PS Where can we find agenda? Official 26C3 site is nearly empty.
