E-mail attachments are one of the worst ways to share large documents. For one, it pushes the hosting requirements for the files to their e-mail provider/recipient. Large attachments will count against a user's mailbox storage limits and can DoS their inbox. The management of that space then falls to the recipient. I also don't know if any e-mail servers that actively dedup attachments. So unless the underlying file system is doing block level dedup a large attachment lives in each recipient's inbox on the server(s). These are reasons pretty much every ISP and e-mail provider has pretty strict limits on attachment sizes. I certainly do not want anyone sending me attachments that are a couple hundred megabytes. I don't want to have to prune my mailbox or choke my mail client downloading the attachment. IMAP and POP3 suck for downloading a lot of data. I'd much rather have a resumable HTTPS link I can download whenever I want. Better yet would be a service that let me preview the document before downloading it. Some sort of dropbox-like service maybe.
