Here’s an idea I’ve been dwelling on for quite a while. Why not make a word processor that stores its files as html. Not an html editor, with the goal of making and posting web pages, but a word processor that uses only document tags that are acceptable in html. You could then post your documents as webpages just by dragging them to a server, if you wanted to. Style sheets would save as css. There could be some automated index creation tools.
Plus, you could also provide a web-based editor that worked the same way; I can log in and edit my word processing files from any web broswer (as long as the files were on an accessable server).
There are several ways to do this now, but all seem to be directed at web monkeys. Finally saw a web-based editor that could do the job but required Windows/IE.
