I am one of the MonoGame coordinators. We have been trying to find a good cross platform advert system for a while now and I only just stumbled across this project.
I downloaded the code and did some basic tests and I am pleased that I managed to use (with some modifications) the ModFox provider under a monogame project on windows. I am hoping to test the code on the Android version of MonoGame as well, then on the
Some of the providers will not work as the assemblies are not available, but I think ModFox should work across all the platforms (and possibly one or two of the others)
Are you open to code contributions? It would be nice if I could contribute the MonoGame code changes/projects back to this project.
