After a conversation with David last year about bug-tracking, I worked
up a rough python-based prototype of this. It worked in terms of
namespaces, so Carl could associate the namespace "public" with a list
of tags he publishes to a http-accessable location. And you could
associate the namespace "cworth" with those same tags.

He types `whatevercommand push public` and all tags "public.*" go to an
config-associated URL.

You type `whatevercommand pull cworth` and the tags come down from that
URL as "cworth.*".

So what he has as "public.to-push" comes down to your notmuch as
"cworth.to-push".

It's available here:

    http://commonmeasure.org/~jkr/git/nm-remote.git

See these emails for more (but note that the repo url has changed to the
above).
    
    id:"m1k4rkkchy.fsf at watt.gilman.jhu.edu"        
    id:"m1hbmokbxj.fsf at watt.gilman.jhu.edu"

There were some details and inherent ambiguities about conflict
resolution, and the above emails explain how I dealt with them. 

Note also that it uses python's configparser, which will overwrite your
config -- which means it'll get rid of your comments. So if you use any
of the config-writing commands, make sure you back up your config first.

Best,
Jesse
