Report Using Bittorrent Sync For Large Scale Distribution Of A Changing, Read-Only Repository in Sync General Discussion Posted December 3, 2014 Yes - a maximum of 50 nodes can be connected to the same key in the current free/personal edition of Sync 1.4. Sync 2.0 will include support for far more simultaneous nodes: "we’ve already increased Sync’s scalability in our lab to 1000 devices" - For more information, please see this blog post Will this support be in the free edition? Or at least could a Pro node distribute to a large number of free nodes? We can't ask for users to pay: it would be a free service provided by an humanitarian organization. In the mean time, is the 50 nodes limit on simultaneous connections or on the total number of nodes configured with the same key? We could begin with Sync 1.4 if only 50 nodes can connect at the same time and the limit on simultaneous connections would be raised to 1000 in 2015 with no limit on the total number of nodes.
