Is is possible to write a browser plugin (one that requires the user to install something is OK) that would allow interprocess communication between the browser and a running instance of Excel (on Windows)? For example, suppose I want the user to be able to click something within their browser, and then have a piece of text drop into the selected cell in Excel as a result. This is certainly possible to do with a regular desktop application and Excel, but I'm not sure if it is possible with a browser, for security reasons.
