For you folks that want to run jQuery serverside, here's a little teaser for a product we're releasing early in the new year, that will allow you run jQuery server side (and much more) , we currently have most of the jquery unit tests working, and hope that the wonderfully active jQuery community will assist in completing those tests (some not being relevant for that environement)
Essentially we have a page serving product that provides a full DOM that can be manipulated by jQuery (or any JS) prior to the page being served to the client. We think it's pretty cool. if you want to get a ping from me when it is avail you can send me a pm to davey at the domain aptana.com cheers davey
