While surfing the net I found an interesting little program
will allow you to use your 2GB gmail account to be used as storage. Files are basically added to your account in
the form of an email with the file attached; you can access the files as you
would with any other network drive, it integrates the storage with windows
explorer. The web address is http://www.viksoe.dk/code/gmail.htm
Actually it reminded me of a similar project I saw a while back
called GMailFS, this allowed you to mount your gmail account as a linux filesystem. After a quick google search I found this
and it seems that it is still being actively maintained.
Im sure neither are very secure, reliable or practical;
still they are a novel use of the free storage being offered to users.
