[mif] Comments on draft-williams-mif-problem-scenarios-00

Hi Carl,

I would like to give some comments on your draft "MIF Problem
Requirements and Scenarios".

First, the requirements:
R4: what does it mean to "not require support for Mobile IP"? Should
it at least be required that MIF does not break Mobile IP (or in
general, any other existing protocol)?
R7 and R8: the charter states that "the group shall not develop new
protocol or policy mechanisms". However, R7 and R8 are both addressing
the support of specific policies.

Second, the scenarios:
- What is the definition of a service in this context?
- How does the heterogeneity of the interfaces affect the listed
scenarios? For example, wouldn't a MIF host with two independent WLAN
connections be in a different "scenario" than a MIF host connected to
a WLAN and a 3G access network? Is it a requirement to let the user
choose when and how to use WLAN and the 3G link? Or should it be a
requirement that a MIF solution makes "smart" decisions about what
network to use?

Greetings,
Dominik
