Is there a maximum number of users I can share/sync a folder with using BTSync? I'm looking for either a hard limit (ie, BT sets a limit) or else a practical limit (ie, performance drops off dramatically when a folder is shared with more than X number of users). I would be interested in any limits both for the Free and Pro versions. The background to my question is that we are developing a private content delivery network utilizing file sharing services, and wanted to check how scalable file sharing is with BTSync. Thank you very much for your input! John
