Understanding the truth in that general statement, 
I would like to know if anyone sees a significant
difference in the number of holes created by each 
approach. Handwaving can go either way, so the 
question is given real topologies and multi-homing
goals, is there enough difference in the number
of holes created to bias the approach?
