Just wanted to say that I think it is really cool that you are working on a plugin for this even though I have not posted any real documentation of the plugin system.
You may have discovered that if you start the program manually from the OSPi directory:
sudo python ospi.py
That you will get any error messages that are generated when your plugin is being loaded. This should help in debugging.
If you have any questions, please post them here.
