We've been testing FSF with 10.2.0.2 and my co-DBA discovered a bug that can cause a split-brain to occur. I don't remember the exact circumstances, but the fix is in 10.2.0.4 which is driving us to apply that patchset. Our FSF testing with 10.2.0.4 has been going very well. If you use WebLogic, it will handle a failover but it requires a patch depending on what version you use. I've been doing new 10.2.0.4 builds with RAC and Data Guard with FSF for a new customer. No issues so far.
