Ok, great picture. Several of us have given you suggestions about the devices you can use for the "cell phone or broadband connect device" in your diagram, any of which will work to connect your computer on the left-hand side to the Internet. As an aside, when I bought it, the Virgin Mobile USB cellular modem called "Broadband2Go" was MS Windows-only as far as Virgin Mobile was concerned. Needless to say, both the device and its drivers were developed by third parties and Virgin Mobile was clueless.There was info available on the Internet about making it work on a Linux box. First time was the charm for me. I've read that Ubuntu 10.10 now deals with this device natively. For any modem you consider, be sure you can connect to it using your version of Ubuntu, either natively or with the aid of Google/Bing/etc. But now for the rest of the story. For either computer in your diagram to initiate a connection with its opposite, it has to know the callee's numerical Internet address (IP), normally obtained via DNS, but DNS expects the callee has an fixed IP address associated with a known symbolic hostname via a DNS "A record". It's conceivable that the cellular modem receives the same IP address from the telco each time it initializes, but I would not be surprised to hear that it does not. The trick is to use a service like dyndns.com to track your (possibly) dynamic IP address and associate it with a known symbolic hostname (something like daveshost.dyndns.org, say). You'll have to run a client on the computer on the left-hand side to make the tracking happen. They are available for Linux. Once you've done that, your computer on the left-hand side is as easily reachable as wiki.linuxcnc.org is. Don't forget. None of this relieves you of the burden of keeping both computers fully secure. The Internet is a wild and wooly place. If you get bored some night, try enabling and reading the logs for sshd, httpd, and other well-known services on your computer. You'll be amazed at how often your system is probed. Like rust, the bad guys never sleep.
