Alan,

You are correctly concerned about flooding, however, I suspect that you're
underestimating the scalability problems of flooding.  Please recall that
it's O(n^2) in the number of nodes in your mesh.  This is a serious threat
to building very large domains.  In addition, the full mesh prevents
hierarchical abstraction within the domain, defeating the other obvious
mechanism for IGP scalability.
