50 Licenses for a Hackathon gathering

Hi Guys,
I have asked early about to get free Rhino/Grasshopper for 50 people for a short period on time.
I know there is this 90 Evaluation, but we want to have a free licenses for a AEC hackathon for 50 people and don’t want to have the possibility that there are some participants that have used Rhino/Grasshopper before and then not allowed to make a installation for the Hackathon.

Is there somewhere we could get that kind of Rhino/grasshopper licences for an event for 30-90 days or somebody at McNell i could ask/contact ?

Looking forward to hear your answers :slightly_smiling_face:

Apart from the 90 day evaluation license, there is no other free license.
