I have been reading this thread and it seems that the big problem is that the GM pays for everything. The players testing out the system get to playtest for free. That is the problem I would try to fix. If a player wants to try the system for free they can check out the free demo and probably get someone to show them around the demo. Playing in a game, however, is a better way to see if you want to purchase FGII. For that I think the player should pay the cost of the floating license. It is a nominal fee compared to committing to purchase one's own license. If a player isn't willing to put up a little money to test out a real game then they probably aren't serious about buying it at all. Furthermore, maybe the money they put towards the floating license could give them a discount on when they purchase their own license. This way the GM isn't financially burdened and hopefully everyone is happy, except for those who want a free VTT.
