I don’t know a lot about networking. I’ve only attempted and failed to make some small multiplayer games. But, I think that if you were in a position to actually have users with compromised systems, you’d also be in a position to hire an expert to close the breach. Maybe I’m wrong. But to me it seems like worrying about licensing fees. If you actually need to pay them, you’re doing way better than the average indie and probably have the means to take care of them.
Interesting. Once it’s ported to 4, I’ll take a look at this for sure.
