This looks really nice. I've always hated how buggy the free hosted Jupyter notebook services are, and setting up a remote server yourself is definitely not a one-click experience. Surprised to see how unrestricted this is (for now anyway). They'll probably see some abuse of the resources soon and add more restrictions. The "etc" from the restrictions section of the faq is pretty broad.

"Usage should be limited to learning, research, general computing, etc."
