You should have a rent license option, like QLab: http://figure53.com/qlab/buy/
I failed in my last enterprise and I lost everything. I have no money for a new license.
But I have some easy VJ jobs next days.
But not enough jobs to invest into a new license (or I pay license or I pay food... je je)
Today one friend is going to let me his stuff, but if I could have the chance to rent a license, it woud be easier.
Think about it!!!
