But to be fair. He is asking to basically program 4 remotes (Him, father in law, kids, husband) for at least 2 different systems plus the whole house audio. When you break it down, your looking at doing basically the work of 8 remotes plus.

Why buy 1 remote only. Buy a remote for downstairs and 1 for upstairs. Or better yet, have (2) mx3000 for you and a few mx900 for the others.

On the surface it seems your trying to over complicate things.
