ahhg, I totally agree and really have good intentions of doing this some day :-)

yep - no change to how that would work form existing SDP

Tried to clear that up a bit in the next version of the draft ...

As far as I understand the TP problems, they are taking on a more complex use case but I've always been a bit confused about the exact scope of that work.

Agree - next version allows a support for a grid ....

Personally speaking, I love posts on list B of the form "here there is a discussion about X over on list A and you should go read it" but I hate cross posting because I end up with duplicate copies of messages in my folders for each WG . I read one and perhaps even reply to it then a week later find the same email in a different folder and am confused about if I had replied or read it. It's easy to say I should use better tools or ways of organizing my email but I've tried and for people reading over 10k messages per month, this is about the best I have figured out how to do so I hate cross posts for threads that lead to real discussion. Obviously there are pros / cons to cross posting and many IETF folks fall into both camps. I'm in the "Anything to never read something twice camp".
