I'm still thinking that one must be able to tear a M9 apart and stick the pieces in a DMR. Since the M9 can handle longer lenses, there should be very little need for any changes to the system other than hotwiring it to interface with the R camera in the same ways the DMR did.
We can print a very sexy new DMR box on a 3D printer for say $100 ish, and if one could get Solms to ship the guts of a couple of M9s, then I think a bit of soldering and a firmware hack would be all that's standing between us and a 18megapix DMR2.0
