It's possible mount your Gmail account as a driver in Linux. richard jones wrote some python that allows you to mount Gmail with in linux. you can use all kinds of unix commands to communicate with gmail like ls, rm, grep, cp, etc. it's an ongoing project in development but it's very cool and allows you basically a 2gb virtual drive of sorts. you'll need to have Libgmail and FUSE at hand to make it work properly. libgmail communicates with gmail while FUSE provides the filesystem. Give it a shot, it looks like it's progressing very nicely.
