I don't think we have a particular interest in interconnecting those two,
as our resources are typically _extremely_ stressed, and we would rather not
reconfigure the installation while it is running.  It will already be very hard
to do what we currently have on the agenda.  I don't really see what would be
gained from routing voice data over voip between OpenBTS and OpenBSC.

What would be an interesting project is to reuse the OpenBTS transceiver code
(but not the layer3 protocol stack + sip gateway) and add a BTS-side A-bis
implementation, turning OpenBTS into a real BTS that can connect to OpenBSC
through A-bis.  If there's anyone volunteering to get that work started, I'd be
willing to experiment with it at 26C3.  But that also not on the actual
production/live setup, but on a second OpenBSC instance.

Regards,
