The developers recently said "in at least a year from now".
For some particular features that we would need before adopting it:

2.6.31:  hopefully ENOSPC bug will be fixed
2.6.32:  ability to delete snapshots

Those are just the two largest bugs that I know would affect us;
there are many other stability improvements scheduled as well.

- Chris.
