yes - thats exactly what I want to do

sounds good - then its flexible and not only for key-tables/list types
I'll have this in mind...

its very important not to mix the smart caching and on/offline scenarios

at the moment I'm in the evaluating phase to see if Riena matches my 
requirements. If I decide to use Riena then of course I'll give some value 
back - one feature could be a smart caching ;-)

I'll come to JAX (have a presentation at the DSL day) and there I'll come 
to Riena booth
