a good extension of this idea would be to have the email client follow relationships. It could see that you've sent copies of a file to the same person a number of times and then suggest that file to be attached again this time. This sort of relationship-centered rather than message-centered model seems to be a natural way for people to work, but current clients don't go very far in that direction.
This reminded me of something that I saw on a visit to Andrew McCallum at UMass. He did some work on the publically available Enron emails, using a social network model that included the content of the communications. You can have a look at the UMass CIIR Tech Report, if you're interested in this sort of thing.
