I don't know if anyone here as ever seen or used DropBox, but its a really really cool looking file sharing application. (currently in beta)

From what I can make out at their website (www.getdropbox.com) it looks like a combination of online storage/filesharing and version control. I'm sure many of us here use multiple computers to manage important files and this kind of backup/syncronization tool might be perfect for the consultant on the road.

Has anyone used this? Does anyone have any invites? I've not been able to try it out yet because I don't have any invites
