I had journaling and buffer commit code, but not any filesystem
personality stuff. Current status is that 2.2 is out (yay!) and
journaling is once again my top priority, and I've just started doing
real testing of basic filesystem transactions (currently only for the
simplest case --- chmod --- but most of the others are relatively easy
to add once that works properly).

The development codebase is certainly being done as a separate ext3fs
but that is simply to allow me to test things without trashing the root
filesystem on all of my test boxes! The intention is that eventually
these features should be merged into ext2 proper, but only if we can
absolutely guarantee that there will be no reliability penalty for users
not using the new code. During the transition/testing period I'll
certainly be maintaining a test tree for ext3 as a separate filesystem
so that people don't have to put their existing data at risk
