http://pythontutor.com/ (my webapp) very small footprint ... just a single simple CGI script. but pulls in 6,000 - 10,000 uses per day. not "large" by commercial standards, but not bad for a free tool made by a single person.

Cool! This reminds me of an object graph visualizer my friend Martin have written for SharpDevelop long time ago: http://community.sharpdevelop.net/blogs/martinkonicek/archiv...
I have to say, I absolutely love your app. I use it when teaching people to program all the time!
I tutored in university and Online Python Tutor came in handy many times, thanks!
