We would like to start work on this shortly after the 4.0.0.Final release. If you have any specific idea's please feel free to post of RichFaces jira, and/or post on the dev forums with more detailed descriptions, etc... These updates would be part of the 4.1.0 release.
Note: one of project changes after 4.0.0.Final is released is moving to timeboxed minor releases meaning you can expect more releases more often.
To see richfaces supporting mobile, it would be exciting....
Keep in mind that nearly all of our components work fine on mobile devices :-) Where they do not we will fix as normal bugs.
What I would like to see if a RichFaces extention that contains mobile specific components.
Thanks. It would be great to have richfaces mobile components.
