Kioku is built with JooseX.CPS for asynchronous interfaces: http://joose.it/blog/2011/02/14/joosex-cps-tutorial-part-i/

Its rather complicated currently but allows to have nearly the same abstractions (TRY/CATCH/FINALLY) for async code.

Yes, Kioku can replace Joose.Storage

I can think of a few advantages for not having the callback as the last arg, it's kind of awkward since store can take an arbitrary number of arguments (what if you want no callback but you want to store a function?). Also it allows you to not execute the store call immediately, it will be suspended until you call andThen() or now()
