Plus, I've already written a web based SLD editor for the Australian Antarctic Division, that we plan to make available for public use at some stage (no ETA yet). Right now only Antarctic Division Data Centre staff can edit SLDs, but the public can download the simple styles that we have in our catalogue:

I'm also working on a java based stand-alone editor that isn't too far from completion (I need time, which I have little of) - It would be really good to be able to integrate a mini-wms in it to render previews using getLegendGraphic reqests.. Still thinking about how to do it... Watch this space...

Subject: Re: [Geoserver-users] R: R: SLD editor [Sec=Unclassified]The benefit of a web-based tool is that anyone can just head
to the one
website and use it, and it can be shared by various existing
open source
products already out there that are based on the web (mapbuilder,
openlayers, geoserver). Also, such web-based tools are
relatively easy
to use with javascript and the new abundance of javascript
libraries to
make the programmer's life easy (GWT, script.aculo.us,
prototype). I've
planned out how long it would take and the difficulty and it would be
quite feasible to make one (maybe 1 month full time). We just
need some
time and funding =)Brent Owens
