I agree with all the points in the list except one. On #5, we have
been required by Tivoli to purchase one server license (and the other
required "network enabler" etc) for each instance of the server software we
are running on a host. Yes it is using the same binaries, hardware, network,
etc., but the word we got from Tivoli was that we were out of license
compliance unless we purchased another license.
