Dan, Jeremy,

I think it depends on your definitions of "having RAC". For me running CRS and ASM in *clustered* mode does mean RAC.

"Having RAC" also might assume having to buy RAC license. Don't take my licensing knowledge for 100% but...
Recently, Oracle allowed using CRS for free to its customers with Linux support. Otherwise, you have to buy at least one RAC license. However, clustered ASM instances - do they require RAC license or not? I would think they do but its pure speculation.
