Great. There is also this: http://dojotoolkit.org/docs/getting_started_with_packaged_dojo.html
Yes Apache and BSD are fine. GPL would not be. Basically as long as we can release the work as LGPL I'm happy. (This isn't a comment on GPL itself just a comment that we want to release under LGPL so using GPL in our stuff would be problematic)
you might check over with the portal wonks on the portal forum and see what they are doing too.. Other than the stuff they're doing with the hibernate people: http://jboss.org/jbossBlog/blog/rrusso/2005/10/18/JBoss_World_Barcelona_Recap.txt
that we don't want to talk about :-)
I've found the ajax-based Rialto Toolkit (http://rialto.application-servers.com/) which supports jsf. It looks nice but it's still beta.
I'm also looking for an jsf and ajax related gui toolkit with an open source licence. Please let me know if you have found something interesting.
I really like openlaszlo.org. I think we could live with it not being JSF/etc if it looked as good as their stuff. the framework is opensource.
