Exactly --- I want to write everything from scratch using django, and I will *not* call wolfarm alpha in any way. I wanted to provide some links to it though, for comparison, e.g. let's say you calculate some integral of 1/(x^4+1), so I thought it'd be cool to provide in the answer (besides the actual answer using sympy or sage) a link to: http://www.wolframalpha.com/input/?i=Integral[1%2F(x^4%2B1)%2C+x] e.g. nothing is downloaded from alpha, and it's the user's problem, if he clicks the link or not. I guess providing a link is legal, but if not, I'll not provide such a link, no big deal.
