Re: Draft on PMIP Localized Routing for traffic offloading

Hi, Alex,

I definitely think this technique could be used within a WiFi access
network as the MN changes from one AP/AR to another.  However, it is
not clear whether the WiFi APs would be attached to the same I-BGP
system as the cellular base stations.  If they are, then great, I 
think it would work.  However, if there are radically different backhaul
topologies for WiFi and cellular it might be necessary to have two
different I-BGP domains and use a global mobility protocol for preserving
an address between cellular and Wifi (I think client-based MIP is good 
for this).

I personally think the PMIP-based LR solutions are kind of ugly.
