Mike,

The interface I use when running/testing scripts using MoI does allow scripts to be reloaded without restarting MoI. In fact, I just use my favorite text editor, makes some changes to my script, save the file, then click the 'Execute' button I've added to MoI to test it.

Hopefully at some point I'll get it all nicely packaged to the point where other people can use it easily.

If you think you are going to be doing this often, maybe I can help you get set up with the system I've got now?
