The student and the project already get a stipend. I'm not certain what it is now, but when I was a mentor the student got $5000 and the project got $500. In theory, of course, the project is getting more than $500, because they are also getting a "free" paid intern for a summer, and (for small projects who might need this) exposure. IIRC, the student gets half the payment on completion of the first half of the project, and half after the second, both on the condition of positive reviews from the org. So if a student just blows it off, they don't get their payment.
