Re: [MEXT] Multiple interfaces problems in MEXT and mif

Hi,

In the current MEXT charter there are several items about supporting 
multiple interfaces, including the following two:

- A document explaining the motivations for a node using multiple
interfaces and the scenarios where it may end up with multiple
global addresses on its interfaces [Informational]

- An analysis document explaining what are the limitations for
mobile hosts using multiple simultaneous Care-of Addresses and Home
Agent addresses using Mobile IPv6, whether issues are specific to
Mobile IPv6 or not [Informational].

I think this is very similar to the scope of one of you documents at 
least, so i would find very strange that the same work is chartered in 
two different working groups.

Moreover, we do have wg documents for these two, but we find very hard 
to find reviewers for those, which makes me think that there is not much 
interest on these. So, if you find a more motivated crew to do the work, 
that would be great, we can either do it in mext or soemwhere else, if 
people feels that needs to be done, but that is certainly not the 
feeling i am getting from the input in mext

Regards, marcelo
