They don't quite talk to each other as much as Jeph Loeb runs the TV verse like Feige does the movies, and Feige gives Loeb a no-no list of things they can't use.
I'd say that's enough to establish that the Kree and Inhumans in Agents of SHIELD and the planned Inumans movie were a part of the same plan and not some crazy coincidence. It's not like the Inhumans was a big franchise that both were going to go after.
All I'm really saying is that the Kree are already in the universe as a part of the planned Inhumans movie and their relation to the main storyline of Agents of SHIELD. Whether they go through with their original plan is up in the air since the movie is in limbo and they may decide to go in a different direction. Agents of SHIELD not really being all that big of a hit in the ratings or critically like the Netflix series have been might well be altering plans.
