I've been using btsync since the alpha and am a bit disappointed. I think the 10 folder limit is completely artificial and agree that it's feels 'sleazy'. In my case, I have 15 and am not using it for business purposes, most of them are for sharing with friends and family. I'm not interested in paying an annual fee for this because I host all the infrastructure! I'd consider paying for a license for each major release. So I won't be upgrading. Soon, I guess I'll have to run the following: git clone email@example.com:syncthing/syncthing.gitBecause now I have a good reason to.
