Drop-in battles and mods?

I'm thinking about adding Lutnik's AI mod on my game but I was wondering how it would affect the drop-in mechanisms: does this still work if you use mods? I guess it depends of what the mod modify (textures, new units, AI...)?

I think this is a key issue and something CA needs to respond to - the lack of drop in connections could be explained by peoples use of different mods. The system could well improved is we were all using the same version?
