Re: on the point of mobility & multihoming

exactly.

Last week, Geoff Huston suggested an interesting scenario:

You take your laptop to the park.  Nearby is a very strong, high-speed
link at a coffee shop.  Some distance away is a much weaker/slower
link.

Traffic driving by disconnects constantly changes your preferred
access point.

This is mobile multihoming.  Although a park venue might not be the
norm, it strikes me as a pretty typical scenario for quite a few
likely situations.
