So according to the terms you're unable to resell the service... so does that mean you can't build a paid SaaS service which uses this as a distribution mechanism for files?
SyncApp is wonderful but I don't feel comfortable with it being closed source and your infrastructure being used. Thus I use it only to transfer files between computers I wouldn't mind sharing with the world.
As for your question, yes, we're planning on releasing a version that will allow for you to use your own tracker - unfortunately we don’t have timing yet for that but it is in the works. We're working hard to make a great product and to support everyone as best we can.
Also, we do have a dedicated forum for the Sync API http://forum.bittorrent.com/forum/106-developers/ in case you have other questions/comments. Thanks!
