FormFu still handles the rendering, validation, etc, but my javascript handles the list contents and filtering.

That solution provides the functionality I want, but still leaves me 
with the 'too much data' problem. Thanks, though. The solution I am 
considering using is to have the clients fill out a pre-form taht I use 
to filter the data. That is a clunky solution, though. I was hoping 
there was a proper way to do it.
