Yeah. ICEfaces has an interesting model. Their AJAX is merely a synchronization between the client and the DOM stored on the server. There are a number of real advantages to the framework and a number of disadvantages.
Trinidad is architected on a different principal. There is a lot of work done directly on the client and their is no server-side Dom. And while ServerSide push can be done in Trinidad with some extensions to the framework, they have to be expressly enabled on a component by commoner basis.
