>> "TurboFloat requires launching of a server on the customer's local network and seems to imply that this must be the same network where the client apps run"
Nope, you can host the TurboFloat Server on the customer's network and then run your app from the cloud or any other network. The examples do show coonecting locally (just because it's easier to demo TF when you install everything locally)
But you can connect to any IP or address on any port.
Let me know if that makes sense.
