Richard, what you plan to do is great. Let me know when you got started and I will help with testing. And yes, in an ideal world I would like to have on "master" instance where I can decide whether to insulate each project or not. But I'm not sure how this will behave with logger (though logger has the option to aggregate each logger instance into a master logger if I'm not utterly mistaken).
Either way, let me know how it goes, looking forward to it.
