 The sections are not possible to enumerate or can be too many to 
 enumerate. Imagine MobileMe, where each section of the web app has it's 
 own interaction (java)script (I suppose). I'm looking for the best way 
 to load that when switching between sections/modules and discarding it 
 when switch back.

 Perhaps MobileMe could have the interaction all bundled in one script, 
 but for a bigger app to have a fast load/response time, the scripts 
 should be divided.. I think..
