[web2py] Re: RIA Framework Recomendation

Whichever you choose, Web2py is just going to be responding to simple data 
requests. I suspect if you need something like the Sencha link you provided, 
Ext maybe your best choice. Two I have not yet seen mentioned that you might 
take a look at are SproutCore and Cappuccino. Flex could be a good option if 
you don't need HTML (no iOS).
