2-machine cluster setup

[jav]

yes and no, as the previous reply to this message from Josip has stated,
you will get increased bandwidth, but the latency is enough to negate
any "real" positive effects when only dealing with 2 nodes.  For
simplicity's sake channel bonding really isn't that necessary.  Instead,
buy the 4 NIC's and be prepared when Murphy's Law takes effect.
