I've been mulling this problem for a few days as we need to do development in parallel with QA running their tests. We do have two separate Oracle instances, but keeping them in sync manually would have been a huge pain. I'm not a DBA, so just looking at the replication stuff made me run away in fear.

Instead, I fired up Navicat for Oracle and (ab)used the Data Transfer feature - makes keeping two schemas in physically separate databases synchronized pretty painless. A pretty damn useful tool! (I don't work for them, just like their tool.)
