Earlier quoted context omitted.
Totally - remains to be seen! Someone should take the underlying realtime datastore ( http://github.com/marcuswestin/fin ) and bundle it with mustache or !
http://github.com/ahe/choco bundles a different js datastore (js-model) with sammy and has mustache support
fin.set(id, property, value)
fin.observe(id, property, function callback(mutation){})
Would be rockin to see if we could hook up fin to js-model!
