If anyone is curious, I'm working on a GUI shell for the python second life client, pyogp.
Temp home for pyogp intro: https://wiki.secondlife.com/wiki/Pyogp/Client_Lib
Basically the [first] plan is to have a GUI wrapper around the sample code with a batch file option, and to allow multiple avatar execution and control in the same process. It's been tested in the command line with up to 20 avatars at once, and the goal is to handle 200 at least, for QA purposes, so the GUI has to handle that as well.
