BitTorent Sync is a great tool for startups.

This piece would have been a lot more interesting if it had mentioned why Sync was preferable to the other solutions.

&quot;Files sync immediately and fast&quot;.<p>So which is it? Immediately or fast? How would the transfer rates to a remote sync compare with a NAS replication stream? How would the LAN file synchronisation compare to local NAS?

Files are inaccessible with a smartphone though, that&#x27;s what&#x27;s lacking. But that said, no centralized server is a killer feature.
