Fortunately, there are many SDR platforms available now. Especially interesting devices are USRP, UmTRX, bladeRF, and recently introduced LimeSDR. They can be easily programmed to support just about any type of wireless standard, of course, including some mobile telecommunication stacks. As well as for network side back-end, they can be used to perform MS side operations, excepting frequency-hopping and some phone specific features (like SIM I/O).
Btw, the first release of XTRX (http://xtrx.io) will have a SIM driver, so it'll be possible to connect it directly to a SIM card slot, as per the miniPCIe standard. If users will find this feature useful for users, it'll make it to the final release.
So, I think there is a way to bring a new live to, amazing child of the Osmocom umbrella, OsmocomBB. We can make one work on SDR hardware platforms implementing a 'bridge' between both already implemented L2/L3 and OsmoTRX.
Also note an 'ms' branch of osmo-trx. It's not a full functionality required for an MS and the code is pretty dated, but it's close enough to start.
I know that there already was some attempts (see sylvain/ms-sdr branch) to make described dreams come true, but development was stopped. And now I am going to start to work around this direction.
It was a combination of circumstances that work was not finished and I would totally support an effort to finish it.
