RE: Proposed way forward with the transition mechanisms

["Soliman Hesham" <H.Soliman@flarion.com>]

Hi Jonne/all, 

I continue to think that ISATAP is a good
solution for the cellular environment and is a 
good candidate for 3GPP. 

To preempt some of the discussion I'll be specific,
I'm talking about:

- host to router model
- Assuming ingress filtering
- Assuming authentication in the network.

I think it should go to standards track. I won't
be in the meeting but if there is a vote count 
me in! 

Hesham
