I just applied the external stored procedure patch to a branch of MariaDB and uploaded it to LaunchPad.You can see the branch at https://code.launchpad.net/~atcurtis/maria/5.1-wl820Note that this is not in any reasonable condition to merge into MariaDB. Hopefully we can engage in dialog as to how we can bring this feature properly to MariaDB, MySQL and Drizzle, hopefully making the plugins
