If it's just for mail, that might be a solution. We did something like that at Tandem decades ago: instead of sending the attachment, send a reference to the attachment. The first time anybody on a node reads the attachment, get it. From then on, retrieve it from the cache. Sound familiar? But I'm pretty sure that's not what they're talking about. They specifically refer to OS files. Maintaining consistency must be a nightmare.
