Yes, we are discussing the problem of interoperability with Sun, and trying to come up with a strategy to test and certify various JSF libraries. Obviously richfaces, woodstock, trinidad and icefaces are the ones we are most interested in.
It is not needed to even mention how important is that Seam will work with top JSF component libraries...
Seems like the list that you've mentioned are of the biggest,
Are there any place to track changes / news related this issue?

Are there any news related to this topic?
I've tried using a seam-gen(erated) project together with woodstock and gave up after ajax4jsf erros turned out longer than their source-code ;-)
