Heh, not to fawn all over a YC alum, but I use Dropbox for all my friend-file-sharing. Just pop it into the public folder, get the url, pass that out via whatever.
Maybe FF's is easier, but Dropbox has made it simple enough that it's not worth it for me to play with other solutions.
Dropbox is one of those products that's so good it doesn't get nearly enough hype. I can't think of any service I've ever used that was any better or more flexible. It's my all-time favorite app.
