On the road but desperately need to fix something on your web server? Wapsh (original link is dead - links to internet archive) allows you to remotely login into a unix shell via your wap-enabled mobile phone. Of course, it's probably slow as hell. And that's if you can get that far without wap crashing your phone. (Can you tell I don't think much of wap?)
There's a Linux distribution for the Sega Dreamcast console. I'm speechless.
