[ppml] Current Info - Policy Proposal 2002-3: Micro-Assignments for Mult ihomed Networks

[Forrest]

I think this is a very reasonable proposal, especially if the wording is 
added that would potentially reduce the minimum allocation in the future.  
The biggest argument against a micro-allocation policy I've heard is that 
it would greatly expand the routing table, even though there has been no 
data showing that to be the case.  I think lowering the minimum allocation 
in steps would eliminate most of those fears and I would definitely like 
to see the minimum eventually lowered to /24.
