Editors for wiki systems
In mobility architectures for wiki, it is important that we have a local editor on local wiki topics and files, which you sync with central server.
So local wiki editing within a browser, with light-weight http server running on your laptop or mobile device would be desired.
Editor in javascript or java applet are not always good options: They should be available across all platforms, should be fast and like native editors. In fact, I am typing this in blogger's javascript editor. Works in windows; probably not in mozilla (well; I never saw this there!).
But flash should offer a good option - it is after all all UI rich and is available across different platforms. (Suggestions welcome!)
Though there are many javascript based editors, we require integration with wiki systems: Primarily performing format conversions. So you indeed require a open source editor.
Perhaps we should wait for mozilla editor control!
