Re: [Ring] Sending failes or takes hours even if my contacts are online

1. The loss of privacy for ring is you need to use a central point 
(explained in the previous mails) which have the authorization to send 
push notifications. Push notifications will not be enabled by default.

2. Yeah another way to do that is polling. You can try to get messages 
every X minutes. The problem is it consumes battery (and it's another 
part and can be used by OpenDHT) and you can also do polling directly on 
the DHT.

3. The push server contains private informations to authorize to use APN 
or GCM or any other solution. So it can't be widely distributed. Any one 
can host a node, but you can only use push servers for your application. 
The way to self host the push server is to regenerate a certificate for 
your application with your device and to host your push server. Again, 
like maxim said, push services are centralized. (But again, push 
notifications will be disabled by default).

4. OpenDHT doesn't say this. OpenDHT just tell a new value is stored for 
a hash. And OpenDHT on your phone will wake up and decrypt the value later.
