Except that it wouldn't be a loan, rather it'd be a scholarship or fund. The student should not be expected to pay it back, so I guess it would be someone like 'ChipIn' in that regards. If the site were built similarly to KickStarter, where the student posted a video and could post their grades, they could more easily solicit donations from friends and family. The organization could send the money to the university as a grant rather than to the student directly to lower the chance of the system being used for fraud.
