I plan on hosting an MP game or games to test my nation mods in MP, but haven't had the time or energy to do it yet. The way I see it, if the mod maker wants to see his mod in MP hosting the game is the least he can do.
Of course, whether or not it works will depend on if people are willing to play in a game where modded and quite possibly unbalanced nations are present.
Still, there are plenty of games being played with Helheim in them.
