PyObjC has changed my life for the better, and I'm still just  
scratching the surface.  The hard part is that I've become dependent  
on it, so when something doesn't work, everything I'm doing comes to  
a screeching halt.  I can't tell you how much I appreciate your quick  
responses in those cases.

OK, I generally rebuild my plugins with the latest versions of  
everything anyway, but good to know.

That shouldn't be a problem.

Have you seen SIMBL?  It's an input manager that loads plugins, so  
you can load arbitrary code into an existing application (kind of a  
gross hack, I know, but terribly useful when code injection wasn't  
working on Intel).  The neat thing about it is how it is configured  
to only load plugins for certain applications, and only for specified  
versions of those applications.  Having a meta-plugin for Python that  
did something similar would be cool.  I think there is something like  
that for Quicksilver, but it would be nice to generalize for other  
plugins.

Someday, in all my copious free time, I may even attempt it myself.  %-)
