    The company I work for was testing these at one time. They did seem to
    work ok. If I remember correctly we did have one or two issues
    getting them to work correctly with some applications and protocols.
    Though with limited knowledge of the product our issues could have been
    caused by misconfiguration. In the end we end up getting higher capacity
    MPLS links.
