CMS vendor Ektron started out as a WYSIWYG widget maker and pretty much made that market through OEM deals with several major CMS vendors. But some customers don't want an ActiveX-based solution, and rich text editors are notoriously finicky, so not every solution works well within any given environment. There are many applet-based alternatives, although they have had a reputation for bugginess. Now it looks like Ephox is coming to lead that lot, announcing recent OEM deals with Vignette and Percussion, enabling those vendors to compete better in some markets (e.g. academia) where Windows does not dominate the desktop. With the rise of AJAX, though, I'm seeing more CMS vendors gaining confidence with DHTML+Javascript rich interfaces. So the days of the thick plug-in may be numbered...
