Good.  I wasn't sure whether the people who owned the Oracle database were
a involved with this effort, or whether you were mirroring their data
without their cooperation.

Maybe, but if you have an Oracle guru, then you should be able to install
the client libraries for Oracle, build something like DCOracle or mxODBC,
and connect across the network.  I suppose that part of the question is
whether your primary goal is "get it done" or "learn as much as
possible."  :)
