[Dojo-interest] my way of running scripts with dojo.io.bind

[Jon Sykes]

Off the top of my head, if you're constrained to io because of the  
posted variables, I'd be looking at using JSON as the return system  
in io bind.  Then set it up so that whatever data you're loading back  
comes back in the form of a JS function that also initializes any  
behaviors that might be needed to be applied to any elements.

In reality, if you're working within an environment you can get your  
arms nicely around - phpBB being an example - you could just setup a  
sort of pseudo API for your dojo application.  So every call to a  
specific piece of data on the server knows what format that data  
should be returned, what will be done to it, and what behaviors need  
to be applied once it's loaded.

Set that all up using things like topics and it could be quiet  
manageable.
