We've just tagged a beta release of sfGridSolutionPlugin our mootools datagrid.

You can checkout the symfony plugin :

svn co http://svn-gridsolution.dev-solutions.fr/tags/beta-1

or just javascript files for use outside symfony

svn co http://svn-gridsolution.dev-solutions.fr/tags/beta-1/sfGridSolutionPlugin/web/js/

we're now working on optimisation, documentation and samples.

GridSolutionCookie will be released ASAP for view state persistance.
