Was thinking more as a "global" queue (like how psql/libpq will go look for a socket to local postgres in "the right place") - and a binary/program "event" could "magically" store ("on") and process ("emit") events in a db file /tmp/event.<namespace><random>.sqlite3 - creating/initializing or re-using db file as needed...

So keep the api, but support cross process queues, more or less.
