And so is the listener. You don't need both running. I installed Oracle8 to test a few months ago and used it's listener to support a 7.2.3, 7.3.3, and 8.0.4 installation. We had one instance running under 7.2.3, four instances under 7.3.3, and one under 8.0.4. The 8.0.4 listener connected my process with the correct instance.

You just need to configure the listener.ora file with the correct $ORACLE_HOME for each database instance you have running.
