Ekoparty "Future Hackers" Sponsorship

I’m working with Ekoparty and another engineer in the “Future Hackers” program. We’re preparing a free Workshop for highschool students so they can learn the basics of Web application hacking. The Workshop will be repeated in two different days and will have an attendance of approx 50 students each day.

We’d like to request if possible to get an account that allows 50 people into the VPN, we were thinking about routing the traffic via a RPI so the students don’t need to setup the VPN individually. This would be for the duration of the Ekoparty (Nov 1st, 2nd and 3rd).

Is this the right channel to request this? Please let me know otherwise.
