Yes but he was also saying that support for the existing RFC to provide 
the RA option does not seem to be present in any of the tools (from what 
I gathered). If the RFC is there then surely this functionality could be 
added.

 From the original message I thought he was having problems getting 
radvd to work at all. This could just be me misunderstanding the mail 
however.

 From my perspective this is one thing that needs significant 
improvement for v6. There are many RFC's/ietf drafts out there that add 
some nifty functionality but support for them in the real world 
applications seems to be lacking somewhat.
