Re: Call for inputs for IETF-62 (Minneapolis) 6-11 March 2005

Thanks Haitham, 

The slides you sent seem to address a topic that may be of interest to the
group. It's normal practice to write an Internet Draft to explain your
contribution before allocating Agenda time. However, the brief presentation
seems to be in line with the Security Considerations of the -arch- and -ule-
drafts. 

I don't want to delay this until the following IETF, so I will allocate some
time in the Agenda to look at this topic (I'll post copies of the slides to
the list when the Agenda is finalised).

I look forward to submission of the ID as soon as the ID archives open.
