That's the issue, the sender should be doing the heavy lifting (serving the file or at least delegating it) what I propose it more of a seamless imbed/download link on files over a certain size. This could be implemented in email apps using services like iCloud, Dropbox, YouSend it etc.. I know that plugins can be added to certain email apps to accomplish this however that is going down the same path that Netscape did with the browser back in the day and is only now being corrected. Seamless is the goal I should not have to upload/copy/paste It should just be able to take a normal attachment and decide how to handle it based on size etc..
