What do you mean by md-mm? If what you are looking for is just being
able to do QM/MM MD, where the QM part is calculated by an external QM
program, we've had this in Amber for a while now, through the PUPIL
interface.

I don't really understand what you mean about DFTB here... It is not
an interface with an external program: The DFTB implementation is all
inside Amber, just as any other QM method available there.
