Hi Eugene. Have you looked at PR1440? There's a patch there which makes 
a number of changes that I'd like to apply first, but unfortunately when 
I did so it broke the demo page and without access to the logs I 
couldn't figure out why.

Sorry to cause a merge conflict, but I'd rather you iterated on top of 
that patch since it's already been reviewed and performs some 
refactoring of the demo script.
