AJAX Tools

Had occasion recently to learn an AJAX tool called "Thinwire"

It's pretty interesting. There are about six tools I know of in this category. Thinwire, ZKOSS, JSeamless, Echo2, Karora, TIBCO GI, and GWT.

They all purport to separate you from the need to write a bunch of javascript and do the comm.

Which is good. I have experience with Thinwire, it appears to be the most java-like (well, it IS java, and ONLY java). Echo2 appears to be prettier, and is also all Java. Karora is a clone of Echo2. The others stray from the pure java idea, with mixed results. Thinwire ONLY does java, which means you can't integrate javascript tools like Simile, FCKEdit, or GMAPs. ZKOSS can integrate those things, but it isn't pure java, which means you are doing a weird hybrid (java, XUL/XML, javascript, html, css).

I would like to be able to take the time to make an example that runs in all of them, to do a solid comparison. but no time at the moment...each of the above websites has demos (although the JSeamless one is all Flash (!?) which is quite curious---I mean, if you tool is really good, your entire website should be built from it, incl the demos), a sandbox tool, and documentation.
