Dropping the layer23 application?

Hi all, I think the layer23 app was great when Dieter and others worked on the TX part of Osmocom but right now it has the potential of disturbing a real network. So it could be changed in a way that it checks if the firmware has TX disabled (maybe even make TX disabling a runtime setting), and then still follow the first assignment, never transmit anything and on a CIPHER MODE COMMAND switch back to the BCCH (or when no enc is used at the release message). comments? holger
