Idea is to split things such way, that compromising component A or B 
doesn't expose A*B=C. You would need to compromise A and B 
simultaneously. And restrict the number, interface and size of the 
components where exploit would grant access to protected data.

Have you seen many malicious exploits out there for IBM's LPAR / z/VM?

Btw, why the heck display server has any access to input methods anyway? 
It's _DISPLAY_ server and not keyboard or mouse server...
