We already have D-Bus to cover sending events to applications, what's really missing is a standard way to enable scripting. I've had a similar idea myself but never got around to implementing it, but I think a standard D-Bus interface applications could implement to expose a scripting dictionary along with a Python/Ruby/Whatever library to implement a more OSA-like interaction would go a long way.
