Browser-based rich text/wysiwyg editors
I went hunting again. There's lots of ideas out there but almost all require winIE (typically 5.5+) Maybe thats not such an unreasonable requirement, but I'm on a mac mostly at home and it just kills me that I can't find *anything* that will work there. Yes I know about liveconnect (script - movie/embed communication) and I know this is not available in MacIE5, but there's got to be a way...

anyhow some urls:

in-page rich editing, and wikis.

uses DOM methods, not browser specific?? But doesn't work in macIE. Would be interesting to find out why - is it the events, the selection ranges...

java1.3 applet with liveconnect
I'm still leaning towards this kind of model, and this one's open source so there's hope there. But without liveconnect on macIE it gets complicated. There are ways to workaround this though. The problem with any DOM based live editing is that in winIE everything gets MSHTML-ized, i.e. turned into crappy proprietary html. If you can generate clean html in your applet, and somehow get that into hidden form values, those can just be posted to the server and it's relatively straightforward from there.
