  1. Let's talk about "unlimited space" for a second, is the 2^305, which is believed the information capacity of universe is truly unlimited? Or googolplex number (10^10^100) represents unlimited storage? Do you believe that any company in the world could hold 2^305 bits of information?

    Unlimited, for most of the companies mean that you can't get above threshold when your monthly payment doesn't cover their expenses and profit.

    BitTorrent Sync synchronize your computers, so whatever these computers could hold - this is your limit. For free. Do you need more space? First you need to buy a better computer and then you will get a bigger space, so BitTorrent Sync could deal with it too, for free.

  2. Dropbox does that, for couple of reasons: it saves them money on harddrive space and network traffic. Which actually makes perfect sense. In case of Sync, it might be faster to just transfer the file, rather than calculate difference and then apply it to the file.

    Having in mind that all files are binary nowadays, this is not as effective as difference for big text files.

    Anyway we have this in mind, however importance of this feature is questionable, of course if leave aside marketing noise about this feature.

  3. 1) if we had a possibility to create our own trackers. For some situations, when I dont have Internet access, or security requirements are so that I cannot even share my "secret-key" with unknown tracker server.

    We already have solution, forgot to mention it initially. You will need one computer with static IP address. For the folder, unselect relay server, DHT. And select "predefined hosts" - enter ip:port of the machine. This machine will act as a tracker and will connect peers.

  4. Tracker doesn't know the secret. It knows pairs SHA1(secret):ip.port (of course this is simplified) to connect different peers that use the same secret. And you still have an option to use DHT, to completely avoid central servers. However DHT is slower and not as reliable.
