I agree with Kent Holsinger's comment about the possible confounding of
gene flow with historical effects.

Maddison and Slatkin's measure of gene flow using coalescents should be
subject to much the same dilemma, that we cannot easily tell history from
geography, even though some information seems present to do it.

In 1982 in Journal of Theoretical Biology I agonized about this for the
case of polymporhic markers.  But little has been done to try to solve the
problem and really find out to what extent we can tell one from the other.
