I have actually solved a similar problem already as part of a different project (bugbot). We associate a set of additional addresses with a thread and can send any thread updates to those addresses. It would require a bit more effort to adapt it so we properly handle bounces, but effectively this does what you're asking about -- replies sent to a thread will be sent out to all addresses we've associated with that thread (via get_maintainer.pl). In a sense, this will create a miniature pseudo-mailing list per each thread with its own set of subscribers. I just need to make sure this doesn't fall over once we are hitting LKML-levels of activity. -K
