There is a company called CodeWeavers that puts out a product called "CrossOver Plugin for Linux." It uses a customized version of wine to run Windoze applications like Shockwave Director 8.5 or Windoze Media 6.4 whenever you visit a webpage with that content. It supports (at least) Mozilla and Konqueror, and it can even change how Konqueror handles certain mime types when you are just browsing files on your own machine.
It's not free, although they have a full-featured "trial" version that nags you with popups every time you use it. It's also not perfect. Once in a while, Windoze processes that run under it have gone "ballistic," but they provide you with a way to kill and restart the wine server from your menu (Gnome or KDE), which also kills those processes. They also do come out with regular updates and bug fixes.
If you want to try it out, download it from http://www.codeweavers.com.
