UMA a possibility in the future?

Hi, I'm a long time lurker into this project and I've wondered something for a bit of time.Knowing that we can use an ip.access nanoBTS to work on OpenBSC, why not adapt OpenBSC for UMA (unlicensed mobile access) standards? I know over here in the US we currently use UMA with T-Mobile over WiFi to communicate back to the T-Mobile servers and eventually off to the GSM and regular ol' networks. http://www.umatechnology.org/specifications/index.htm is the UMA specification, and to my knowledge T-Mobile US's @Home service uses the 1.0.3 protocol revision. To me it seems like it'd be trivial to make a derived copy of OpenBSC with UMA support up and running, but I'd like some other thoughts into this matter. I'm not a programmer by any means here, so if this is impossible, well, then so be it. -DC
