Gmail Filesystem provides a mountable Linux
filesystem which uses your Gmail account as its
storage medium.

gmailfs is a Python application and uses the FUSE
userland filesystem infrastructure to help
provide the filesystem, and libgmail to
communicate with Gmail.

GmailFS supports most file operations such as
read, write, open, close, stat, symlink, link,
unlink, truncate and rename. This means that you
can use all your favourite unix command line
tools to operate on files stored on Gmail
(e.g. cp, ls, mv, rm, ln, grep, ...)
