    Right now wee are also looking into the same question with the help of
    Overlay Routing. As far as Multihoming is concerned, there is a good work by
    jenifer rexford
    http://www.cs.princeton.edu/~jrex/papers/multipath06.pdf>.
    In fact IETF guys were thinking to include it in BGP implementation.

    Hope it would be helpful
