Already I can tell that there is one feature I'd like to see in DropBox, the ability for a person to receive a code to link their DropBox account to yours.

My fiancee wants to have her files on her computer and I want to have mine separate on my own machine. We want a central repository for some files. Right now with DropBox you have to use one user's account on both computers to get at the files... I'd like the ability to simply "link" accounts.
