It sounds like it might work (caveat: I haven't tried it yet). The best info I could find on it was this paper[1]. It gives some command line examples, explains how the data model works (spoiler: it's similar to git) and provides some benchmarks. The NFS comparison benchmarks were very interesting (generally faster over a WAN than NFS is over a LAN).
Thanks for the link. "Ori over a WAN outperforms NFS over a LAN" that's a ridiculous claim, maybe if you ignore bandwidth. I might have to give this a shot though. I hope it's stable.
