Fernando just emailed me with this info on some Flash Wysiwyg editors that are starting to be developed:
I just found some great examples of HTML edit controls made in Flash MX and I thought it would be intresting for the Wiki stuff. If I remember it right you mentioned you we're looking for something like an advanced editor for HTML.
I found it at Jeremy Allaire's Weblog.
That's cool. A wysiwyg editor would be nice... but I refuse to use Flash. I've decided that flashing logos and window popups and all the other crap that Flash-adverts do on the web weren't worth it and ripped the dlls out of my Mozilla plug-ins folder. If I need to see something in flash (like to see the above links) I just start up IE - in all it's pop-up-window glory... I can't believe how bad it's gotten - and use that to see the flash site and then go back to Moz.
It's in my ever-growing list of things to do. Along with my Linux, blog dev, Java certification and general world-saving activities.
