Here's the official word from Oracle copied from an email I just received

Hi Daniel - Answers to the first question:
  1. RDBMS (i.e. non RAC): yes we support containers, i.e. projects and zones See Note 317257.1 in MetaLink
  2. RAC/CRS/PCW: we support only limited containers, i.e. projects yes but local zones NO, i.e. all RAC/CRS products MUST be running in the global zone. See Note 435464.1 in MetaLink
  3. GRID: doesn't support projects and doesn't support zones. There is an Enhancement Request logged on this one.

Hope that this helps.


So there it is ... you can use them ... but best pay attention to when and where.
