I was mostly referring to the interaction - ways of organizing Horde 
applications so that a single AJAX interface would always know where to 
find a Form instance to get validation information from - that sort of 
thing.

Excellent. That's definitely the direction we want to go with 
additional javascript, including AJAX in Horde.

If necessary you can always resubmit your application and ask Google to 
disregard the previous one.
