Is it possible to create a CODEC-IPR mailing list (or some such) to allow folks to use the alternative list when chatting about patents and work-arounds? That would address some of Stephan's concerns, but still allow the discussion to archived to an IETF list. I'd prefer to keep out of the patent discussions, I suspect there are others who would rather not get those posts either.
