On a whim, I tried out RoughDraft 2.11 under wine-20031118 this morning. It installed and ran with some anomolies (e.g. the installer's EULA doesn't display at all!, .doc import works really poorly, a few pixels misplaced here and there, can't invoke web browser to display help), but it might be good enough for some users.
It's a free download at http://www.rsalsbury.co.uk/rd.htm and I recommend it as a test app. His FAQ says no Linux or Mac port is planned, so there must be interest out there, and he'd probably be tickled pink if Wine improved to the point where it ran his app well enough for aunt Tilly to use. Sources not available but the author seems like a good guy, and would probably be willing to work with us if we really needed it (especially if we fixed a few things first, like that EULA display problem). - Dan
