I actually had this problem, and tried to use Dropbox, but Dropbox does not fully solve this. Last time I checked there were two options for transferring large files on Dropbox. (1) if the recipient has dropbox as well you can just share the file privately. (2) If the recipient does not have dropbox, then the only way to share the file is to put it in a public folder where it will become publicly accessible to anyone. It is obvious that this does not solve things for all situations. In my case I had to send a copy of our software build to a potential client. I did not want to make our software build public. And it would be certainly considered rude to ask a potential client to sign up for dropbox just so they can test our software. I think most HN readers kind of assume that everyone has dropbox by now, but this is not something you can rely on once you get out of the US tech sphere. So yes a service like this would be pretty useful.
