The MMA concept makes perfect financial sense but most of the "Other Govt Dept stuff" is not in a URD and not in DSD13 therefore there is a limited formal Defence requirement for it.
To get this off the ground one of the three (of the four who care) commands would have to give up their envelope to fund it or get together in a gang and "agree" to jointly fund it.
I am not getting that joined up feel.....
