Well my patches to libosmocore implementing GEA3/GEA4 are pending in the list
awaiting review for months :)
I hope to finally push Holger into merging it during upcoming OsmoDevCon this week.

After that you won't need any 3rd-party libraries but I think there got to be some
changes made to OpenBSC in order to support that. Most importantly - we use sqlite as
HLR at the moment which makes it impossible to handle GSM and GPRS auth. requests at
the same time. I think we need dedicated AuC/HLR which is fully async and can hide
sqlite ugliness from the rest of the code in order to make it work.

Not yet, but I'm looking forward for your results :)
