I guess it depends on your definition of useful. I've been using it since 1.4 to do things like: - PBX configuration (e.g. dialplan and routing) - email monit

I guess it depends on your definition of useful. I've been using it since 1.4 to do things like: - PBX configuration (e.g. dialplan and routing) - email monitoring (e.g. monitor multiple email accounts and multiple folders on those accounts) - interacting with API's (e.g. creating a supervision tree that has multiple API accounts making requests) - processing huge CSV files in chunks and storing them in a database Of course you can add Phoenix on top of these to make them more useful.
