A terminal users storage box. When you login, you get allocated some storage space on an NFS, which you can manage using rsync, sftp or scp.
SSH to bypigeon.net and you can access everything from there. Don't worry, it's free, however it is limited to 100 people currently, after which it will be invite only - just while things gets smoothed out.
You will need to be invited by someone who already has an account, and invites to spare.
