I've tried it a bit. It's the most viable and promising so far I think. I have too many directories for it to be usable without some new features, though (namely highlight dirs with new mail and more filtering capabilities). It's practically unusable, but granted I may have an unusual setup. If you just have a handful of active folders it might be great. Didn't notice any surprising syncing issues so far.
