How does it compare to ObjectiveFS (a commercial offering) and S3QL (now abandoned)?

Would JuiceFS be suitable for a handful of servers (and mobile laptops) with connection latencies anywhere from 5-150ms accessing the same file system? Workload is basic home directory stuff (lots of tiny files, few large ones, read-heavy, write-rarely). I wonder about the operational complexity in running the metadata server (yet another thing to manage unless outsourced); if it goes down, do all fs operations block/fail until it's back up?

I'm looking for something like the now-abandoned s3ql file system but one that allows multiple hosts to mount the same volume and have reads/writes "just work" without conflicts.
