True.  But you did send the iframe off to edit something, like a  
topic, so you could check if that object had changes since the time  
you launched the iframe.  If someone else updated it it might be nice  
to get the latest anyway.

I agree, this is all rather hard. Does your app want to edit known  
properties on the topic, or just generally update it all?  If the  
former perhaps google code needs a form element based property update  
library...
