Yep, I think that's implied, since othewise we can't detect which MAS
instance the client is trying to connect to (if I read the spec
correctly).

Since we're primarly conserned with supporting only SMS for now, I think
it's too early to start adding complexity to the code due to this
feature. I.e. let's get working MAP with SMS support integrated upstream
and only after that start looking into these more advanced features.

We'll need to reserve some channels for additional MAS instances.

Do we need to change something there?
