How do I use Gmail As File server?

Hey, even I would like to know this 'coz I dont know the real implementation (of using Gmail as FSS)!! I have a amateur-ish implementation to use Gmail as FSS although I dont use it myself. When you have a Gmail account, you also get to invite (or give away) 50 Gmail accounts. You can use one or two by sending the invites to multiple email ids you have, and once you store the files on the account, you can pass around the username and password (among your trusted circle).
