The problem of online play, as I see it, has nothing to do with fairness, but everything to do with compatibility. As Trooper et al have said, there are mods coming out every other day. Where this is going to be a huge problem is with the maps and aircraft that the host has installed and included for each mission/DF map. That is where the challenge, or frustration is going to come from. We have already experienced this while trying to conduct an SEOW campaign with MODs installed. The multi crewed aircraft are what hair lipped those who didn't have them. But even that could be overcome provided that the single seaters were assigned/tasked first. Now, once we start dealing with multiple versions of the Slot, it's going to be even more difficult to make sure that all participants have the necessary mods to join.

totally agree with you, compatibility is the key
