I heard you about the "limited hands, infinite wishlist" but nowadays when I see someone making bold claims about transactions and consistency over the network, I grab my popcorn bucket and eagerly await the Jepsen report about it

The good news is that you, personally, don't have to spend the time to create the Jepsen test harness, you can pay them to run the test but I have no idea what kind of O($) we're talking here. Still, it could be worth it to inspire confidence, and is almost an imperative if you're going to (ahem) roll your own protocol for network file access :-/
