One of ZK's creators, Tom Yeh of Potfix was recently interviewed by Agile Ajax. In regards to ZK versus Echo2:
Echo2 assumes UI designers are Swing programmers, while ZK assumes many of them are not programmers.
In respect to Google GWT as a competitor or a compliment:
Both ... From a technological viewpoint, it is a complement. GWT is a client-side solution and quite good for developing Ajax components ... It would be great if we can leverage GWT's power to simplify the effort of component development (as we did with DOJO and FCKeditor) ... From a perception level, users might see it as a competitor. Google is now at a sweet spot with plenty of resources and a good reputation...
ZK features a dual license model. Commercial pricing options include per-devleoper, per-cpu, and royalty-free. More information can be obtained on the ZK website.
