The flip side of this is that it's hard to do anything beyond the standard library for some languages. Using PythonAnywhere is great for std-in/std-out programs, but I couldn't figure out a way to import graphics libraries and such. The web is pretty limiting when teaching with anything other than JS/HTML/CSS.
