	What happens here is essentially that ~~the~~ the kinetic impact energy of A gets chaotically distributed to all the atoms of B* (it gets thermalized/devaluated).

At this point we can justifyably say that a permanent bond has been formed.

	If the mechanics in the background of advanced mechanosynthesis mills would be infinitely stiff it would behave as just one single degree of freedom. In reality the mechanics in the background have some elasticity though. Coupling mechanosynthesis mills together which are too far apart will likely include modes of elastic thermal oscillations making it behave as more than one degree of freedom containing more than one thermal energy packet of k_B*T. Gearing may help in coupling things together that are farther apart since gearing can create a higher stiffness in a virtual way.
