:Clustering over LAN or WAN is good, but aren't high speed links 'icing 
:on the cake'? It's possible to be able to do either/or isn't it?

    Algorithms designed to operate over a WAN will work just as well over
    a high speed link.  But algorithms that are designed to work on high
    speed links tend not to work all that well in a WAN environment.  For
    example, someone who doesn't have to worry about a ping time of 25 ms
    might design a simpler cache coherency mechanism that depends more on
    fast full duplex communication to be efficient.
