Notes/FX on the web (or similar)

In some cases, our web application cannot “flex” enough re: unique/custom docs. Someone might want to paste a table, images, etc… I thought about Notes/FX… but this is a web application. I know that Quickplace lets you incorporate a MS Word doc (template) into a form and force users to use. It would be great if an external editor (e.g. Word) could be launched + pass salesID # to new doc. Is this way out there? …any ideas?
