We will see how to interface it from our cabins with from the sim. I do not know how FS is now dealing with addons. I read "LVar and offsets" are no more in the normality. We will see.
As I hear it, there are beta versions out for FSUIPC, LINDA and Air Manager, so I think it is safe to expect we will be able to interface pretty much as we do now. (Of course I haven't tried any of those things yet )
