Interesting...
Here is the quote from 10.2 docs:

CLUSTER_INTERCONNECTS provides Oracle with information about additional cluster interconnects available for use in Real Application Clusters environments.

The CLUSTER_INTERCONNECTS parameter can be used to override the default interconnect with a preferred cluster traffic network. This parameter is useful in Data Warehouse systems that have reduced availability requirements and high interconnect bandwidth demands. You can also use CLUSTER_INTERCONNECTS to override the default interconnect chosen by Oracle.

For example, if you are running two instances of Oracle for two databases on the same machine, then you can load balance the interconnect traffic to different physical interconnects. This does not reduce Oracle availability.

So it does indeed look like it should work! Obviously, it's only working with IP. If your use third party clusterware (like Veritas) and use interconnect over LLT, for example, than this is not needed. I wonder if you can force Oracle instances to use UDP instead of LLT, for instance.
