Well, I've worked out the second option. My .htaccess file now looks 
like this:

SetHandler python-program
PythonHandler handler
PythonDebug On

This sends ALL requests to stuff within that directory to handler.py's 
handler() function. I've drawn a blank on getting it not to do this with 
images. I tried the following:

AddHandler default-handler .html .jpeg .jpg .gif .css .js
SetHandler python-program
PythonHandler handler
PythonDebug On

But this didn't work - presumably because the SetHandler over-rides the 
AddHandler directive. I tried changing their order but didn't have any 
luck there either.

Any help on this would be greatly appreciated :)

Thanks,

Simon
