What, exactly, do you want to do with it, and how does it replace email?
(Genuinely curious - I see suggestions for replacing email on a regular basis, but rarely ones that are deeply thought out.)

One of big potential benefits I see is the XMPP concept of contact requests. Simply separating new senders from existing senders at an architectural level seems like a great start for an email replacement, both in terms of user experience ("who I know" is fundamentally separate from "who I don't know" regardless of the client), and in network utilization (spam is only ever as long as a request header instead of an entire message).
Because in the end, and despite all its kludges, e-mail doesn't need replacement. Its biggest problem remains spam, and even that is under control by all the major providers.
