Just to stay on simpler ground, what would prevent a software evolved
enough to have multiple instances running in different servers, in
different places?
And have every instance with a share of a Shamir Shared Secret.
Then an attacker would need to compromise M of N instances in
geographically different servers.
If an instance is compromised (as judged by the others) the other
instances rent a new server somewhere and seed a new instance with a new
set of SSS.

And why should they sit in some server forever when the instances could
change servers periodically?

Just to add to the difficulty of the attack.
