For example: if you have an active ssh session and you switch the 'underneath' transport layer from WiFi to Cellular Data or from Cellular Data to WiFi, the ssh software should (and it does) keep track of disconnection / re-connection and resume working as if nothing happened, provided the time required to reconnect is short enough....

For VPN connectivity I use SecureFishNet: it's not opensource, but I haven't had time to solve my VPN problems with Connmand
