We have 2 callers today, in the future, can you envision this API getting more options? If so, in order to avoid the pain of collateral evolutions I can suggest a descriptor being passed with the required settings / options. This lets you evolve the API without needing to go in and modify old users. If you choose not to that's fine too, just figured I'd chime in with that as I've seen the pain with other APIs, and I'm putting an end to the needless set of collateral evolutions this way. Other than that possible API optimization: Reviewed-by: Luis R. Rodriguez <[email protected]> Luis
