Imagine two company X and Y, in the X company the spark user’s are connected to the Xserver and in the Y company the spark users are connected to YServer. X and Y are connected via VPN.
Imagine that the VPN fails,what I want is to allow the communication between the users of both companies even though there is no physical connection between them. Is this possible?
simply shout, let it out loud, these are the things you can do without a VPN. There’s a slight chance that users from company X and Y can shout so loud that they can still communicate.
Anyhow you can use a s2s connection over the Internet, there’s no need to use a VPN.
The idea to allow communication without a physical connection is quite interesting and likely already patented.
