[Softwires] Re: Proposal for extension of Radius Accounting

Hi all,

I published a draft explaining the problem :
http://www.ietf.org/internet-drafts/draft-stevant-softwire- 
accounting-00.txt

I wont be present at the Interim. Laurent Toutain will do the  
statement for me.
Have fun in Hong-Kong :)
