Jon, just to let you know there was an article in the last Archive by one of our users who uses his RiscPC and Mpro to happily make his email available wherever he is in the world. He was able to install Mpro server, go away to Japan for a period, read/write email from cyber cafes and then return to continue work on his RiscPC once home, then head off again. This sounds quite similar to what you describe, and that was using the older versions. We've made this even better in recent releases. He's currently beta-ing some other facilities which were requested too. I'm citing this example, as it shows that pure-RISC OS can make an excellent job of achieving what you mention in your message.
