I'd be very interested in seeing some Crossfilter-based filtering store code. I've been working on a business application that needs to do quite a bit of filtering and hierarchical rollups, and I'd really like to start using Crossfilter for it so we can chuck the much more limited tool I whipped up when we started the project and get that speed boost you mention. We're also starting to see a lot of the many-to-many relationships in actions you mentioned, which convinces me we need to work towards more of a Flux architecture (it wasn't out yet when we started this lo those many months ago).
