That's a great suggestion. I appreciate being able to control use of tracker server and relay servers but If I had to choose I would rather just have a "lan only" since those two other options are probably going to be used in 99% of the cases to lock down lan only. Mostly I wish i had a way of making it lan only without having to do it by forcing at both ends. Maybe on one machine I want a directory to only sync on the lan but on another I want that same directory to sync no matter where. The way the options are set up now I'm pretty sure that unless all machines have tracker off you end up synching because one can find the other (I may be wrong about this but I think in my test that was the case).
