Apparemment, PSI a reçu une license pour windows gracieusement de la part de trolltech. D'après Justin Karneges sur dot.kde :
"I just want to mention that the Psi project (http://psi.affinix.com/(...)) receives Qt/Windows for free. Trolltech gave us 3 commercial licenses, including support and upgrades, provided that we only use it for open source work.
I don't know how common it is for Trolltech to do this. Maybe it helped that I was a Qt customer in the past. Maybe we're the only such project. In any case, if you have a popular and dedicated free software project, you might try asking them to help you out. :)"
