"Petersen showed us the C-compiled versions of Lua, Ruby, Perl, and Python all running on the web in secure Flash sandboxes."
Nevermind that he then goes on to pick embedding Python as the topic of the blog, since this quote is the one drawback of it: "t also means that we get all of its flaws along with it?such as the fact that the standard CPython distribution is a few megabytes large"
The lua interpreter doesn't have that drawback! :)
