"Dropbox for VPN"

"Dropbox for VPN" makes no sense whatsoever, and even after reading the product description, I don't understand how it related to Dropbox at all.

Who has the appletv?<p>22:39:02.409865 IP 29.215.211.78.5353 &gt; 224.0.0.251.5353: 0 [7q] PTR (QM)? _pdl-datastream._tcp.local. PTR (QM)? _appletv-pair._tcp.local. PTR (QM)? _appletv._tcp.local.

(246)<p>Authentication is based upon an API call to <a href="http://api.zerotier.com/one/nc/randomhash" rel="nofollow">http:&#x2F;&#x2F;api.zerotier.com&#x2F;one&#x2F;nc&#x2F;randomhash</a>. That returns a config file which includes the IP that you are given. Seems like it would be highly susceptible to an MITM attack.<p>Seems like an neat idea, creating an massive network on top of the internet, but how private is a VPN if it&#x27;s free to signup &amp; all clients are put onto the same &#x2F;7 subnet? Isn&#x27;t putting every client on one network less secure than how the internet normally functions?

So it&#x27;s a massive broadcast network?<p>Where does Dropbox come into this?

Perhaps it&#x27;s because I just woke up 20 minutes ago, but this makes zero sense to me. What am I missing?

Oh, so it&#x27;s Hamachi, but public and private, and installing it on Mac doesn&#x27;t require a hack. Ok.
