Why? What is consuming these outputs? If you expect people to use their browser to view a JPEG, for instance, then you'll have to serialise it as a JPEG won't you? Maybe you could consider using the ZipSerializer to create a zip file containing your binary file and a manifest file (like a JAR file, for instance).
