Doh!
Well, it's not impossible to get mobile working on linux, but we never found a repeatable set of instructions for doing so. Some people have managed, however. You'll need to at least be using Oracle JRE 6 (not 7! Mobile won't work on 7).[/quote]
Another heads up: you can run a headless server, but you'll have to install x11 and make sure everything is configured since the mobile module makes a virtual screen session.
