In the straw poll, Steve Dietz said it was "not clear why license is for this time period only".

Each license will have a time period and a price, obviously. One year was chosen for this sample because it in the MESL project universities noted that it was difficult for them to agree to multi-year licenses due to their internal budget cycles. Probably a fee structure could be offered which made it advantageous to license more than a year at a time, and this might be an option for AMICO. David
