Perhaps communicating out of species is difficult, they must learn how the neurology of the other species works or they just send static.

Well, it is already harder communicating with other species. Between Simulacrum it's a very strong connection; they just automatically feel the surface thoughts and emotions of all the other Simulacrum around them and then also communicate via thought and can tell where others are (they can teach themselves to stop sensing others and suppress their mental link to others though). But with other species, it's essentially just communication. But I'm still working out all the little details and whatnot, and it does make sense that there'd be difficulties when communicating with new species.
