Hi ste7an and others,
It seems HSL does not want in any way be associated with OpenBSC and actually think it is a bad thing that we have made our software interoperable with their product :(
So it seems we have to continue to look for (and/or work on) other alternatives. I have some ideas but it is too eatly to talk about it.
I do not know of anyone so far using/deploying their cell. -- Sent from a mobile device, excuse my short response
