That what I had in mind. I agree that this solution would not scale to
Dom10 and beyond. But that ring solution is not going to be any better.
Let's imagine you want to switch between domain 9 and 8. You would need
to type CTRL-AAA N time before reaching the right console. N been the
number of domain you have using the console.
It feels like, you want to provide a key for selecting the console (e.g
'c') and then type the domain ID you want to access. Can you read
another key when in the keyhandler?
Cheers,
