Open an issue in the Live repo about this. SymPy Live will need some serious refactoring in the near future anyway in order to keep it up-to-date, since the current setup doesn't support Python 3. I'm still hopefully that we can replace the backend completely (this would be a good GSoC project for anyone interested).
