In forms6i you can program the functionality in client-server mode, I believe you have to go to forms9i to get the add-in that supports client-side funtionality like this.

Can you install HTML DB and have the users download the documents from the database via that? They you get your mime-type functionality back and MS-Word automatically loads from the browser.
