I'm not sure i understand what happens.

In itself just cracking SSH is rather easy for governments,
it's just 1024 - 2048 bits RSA, and they can factor that with a  
reasonable beowulf cluster with
special hardware quite easily. You can already prove this for a  
rather old algorithm to be the case,
and i'm sure the math guys got up with something much better nowadays  
- so will China.

So what's the scan really doing, is it a physical verification of  
where you communicate from, so a physical adress,
so mapping every user on this planet to a specific physical location?

How sure is it that China is behind everything knowing they already  
can crack everything anyway?
China gets everywhere the blame, in the meantime i have lots of  
Irani's lurking around here.
