Editing documents and saving to database

Hi, in our application a user is able to retrieve a dcoument (typically MS Word in terms of its origin and mimetype) from the system (this is a 9i / mod_plsql / iAS application running in a browser) and we display this in a browser window. A user has asked if they can edit the document and then "save it back to the database" perhaps under a different name.

My guess is that this is probably possible but perhaps not with the technology we are using at the moment (see sig).

Any suggestions?
