This is a great recommendation and can be easily automated.  In your
personal ssh config, usually ~/.ssh/config you can add in:

Host *.dreamhost.com
        ProxyCommand ssh -q shellworld_host nc %h %p

With this in place, you'll be able to just type 'ssh yourhost.dreamhost.com'
and you'll bounce through shellworld_host (substitiute your actual
shellworld host account) to make it mostly seamless.
