Integrity is resolved at master level (if you just update values, not keys).
Snapshots do NOT have constraints, primary key, etc... (by default) and Oracle tells you not to create any constraint that could interfere with the replication process. Haven't tried it, but user constraints might be ok, provided you disable them before refreshes and enable them afterwards.
As for indexes, feel free to create them :), but on the SNAP$_table (the snapshot is really a view).

That's exactly what multi-master is for.
