Knowing how the Legacy signal works, I think I can answer this for you. Don't hold your breath for Legacy to be two-way direct back to the base without other products in the mix. TMCC and later Legacy are strictly one-way protocols at this time, major hardware changes to engines and command bases would have to take place to change that. You're talking a whole new product when you start talking two-way from the engine back to the command base directly.
