The Client API ExtCake.registerModel(modelName,option

s) ExtCake.loadModel(modelName,options)

clientName: the clientside model name forceConsistancy: use the consistant model

ExtCake.loadTemplate(tplName)

The Server Classes RemotableBehaviour DirectController

Router Data-Schema

DirectComponent handles RPCs

TemplateHelper provides templates to

cake and ext views

So we gotFast and reliable RPCs

Synchronized models

Shared templates

We will also haveSupport for Sencha TouchPHPUnit-, Jasmin- & Selenium-TestsPolling Model

Polls the server for changesRapid Development

Command Line Tool

What else?Lazy Loading
