Hi! Basically, this is just for playing around with. I fully intend to run it more securely whenever I set up for real. I will shut the server down in maybe a week, once I have everything functioning properly, but I will keep my account with RackSpace open so I can crank it up again when I need it, and that version will use all necessary security and be left up permanently. It is using the MOSSO cloud server and is very much virtual. A server can be deleted or created in a few minutes at will priced by the hour according to resources desired. They offer any of about a dozen flavors of Linux to choose from. Check out cloud computing and cloud servers at RackSpace for more info. You can run as many separate servers as you are willing to pay for. You can also change the resources allocated to the server whenever you like to account for busy times for extra capacity or slack times for economy. For right now, it is for experimenting and playing around with, but I will follow all your suggestions when I set it up for real. I will experiment myself to make sure that I know how to implement the mentioned security measures when I need them

You do realize that any user could trivially delete all files on that server, kill the notebook server process, etc. You need to setup a normal user (not root) to run the notebook server, the add a second user, setup ssh keys, and use the server_pool option. This is explained in sage: notebook? I assume this is a Xen virtual machine at least, so you don't care if users break the server somehow... since you can just reset it?
