Andrew, it looks almost certain we'll be going with 9i. When I started asking around I heard a lot of doubts about 10g and very few about 9i. Coincidentally, on Monday Oracle had to pull the 10.0.3 patchset on some platforms because it was causing CLOB corruption; I'm sure it will be fixed soon but still, I think going to 10g right now is more adventurous than I want to be.
Also, FWIW some people feel that the 9.2.0.5 patch is buggy and are recommending sticking with 9.2.0.4. Others say it's fine, so YMMV.
