I read on LWN today something interresting..

http://lwn.net/Articles/99933/
Version 0.2 of GmailFS has been released.
GmailFS is a fun hack which allows a Linux system to use a Gmail account as a remote storage device; it can be mounted as a normal (if, perhaps, slow) filesystem.
It's a user-space filesystem written in Python.

you will need python, libgmail and AVF's FUSE

With FUSE a userspace program can export a filesystem through the Linux kernel.
libgmail is a library to provide access to Gmail via Python.

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 etc. etc.).
sounds like fun
will try later today.. I'll keep you posted
