Jonathan's questions

I'm working on a network where I can't obtain a public IP address or set up VPN access. Is there a way that I can communicate with a local server remotely by using an intermediary in the cloud that both local server and remote client make an outbound requests to? If the local server would be making a request every few seconds to a public intermediary (EC2) to see if a remote client is waiting to speak with it, then the fact that it doesn't have a public IP wouldn't matter. At that point, I could also make a request from a client at a remote location and somehow ssh into the server through the public intermediary. This way both the client and server are initiating with an outbound request, which can originate from a private IP, without any modifications to either local network. Any bright ideas?
