Unfortunately, as (I think) all SQLite replication solutions, it requires you to run a separate process on each app machine. It defeats the purpose of using SQLite in the first place; if I must have an additional process to monitor and maintain, I might as well just use Postgres or MySQL
But with Postgres or MySQL you have 2 additional processes to monitor: the database server and replication
...or you can just use managed variety and not have to worry about monitoring anything db-related
