Just to be clear... is it okay to make a "hot backup" of that file
while the server is still running? (I would think so, give it's
append-only storage design.)

Other databases (Oracle, Postgres) make a big distinction between hot
backup (while the server is running) and cold backups (when it's not).
Usually, the safest backup method with them is a cold backup -- but is
impractical, given the downtime. So, usually, those other dbs ship
tools to "dump" the database to another file as their hot backup
solution. If "hot" copying of couchdb db files is safe and a "for
free" feature of the design... that's really, really cool. :-)
