Sam Bisbee commented on COUCHDB-1296:
-------------------------------------

@Jan: Sorry, not sure I follow you. You closed this ticket but now think it's a 
good idea? Or...? :)

Also, one possible solution to this is to have CouchDB store database data in a 
database (ex., _local). Then we get the _changes feed for free. Don't know if 
that would be any easier to build than hooking into the existing on database 
create/delete functions.
