Frank, I think you're wrong Here's an example, Lotus Notes Client let you configure which browser to launch to open http link embedded in email. I've configured it as "z:\usr\bin\firefox" and whenever i click on a http link in an email it launches flawlessly firefox for linux pointing at the right page. Moreover, I've made a script that associate every mime type known by linux in wine so that whenever a windows application has to open a file wine can launch the default, in my case kde, desktop manager application associated with the extension.
