I still wish there was a popular, easy way to send large files directly, without using 3rd-party bandwidth. This requires the file to be available on http. If my grandma wants to send me a large video clip, she's not going to know how to put it on a web server. (Also, a web server is 3rd party in this case.) IRC direct connect and AOL's IM client are the closest I can think of, but neither are at the level of popularity/ease-of-use for my grandma, not to mention the technical hurdles of firewalls (and the security concerns firewalls are addressing.) As far as I know, this is an unsolved problem that has created a work-around market (dropbox, rapidshare-style services.) But perhaps the work-around market exists for a reason: there is no revenue in letting users directly connect to one another.
