Yes, this works in theory, but as CA certs recognised by the main
browsers are effectively a license to print money, the certs you get
from the existing recognised CAs have the "can be used to sign other
certificates" bit disabled. It's an oligopoly-protection mechanism.
You *can* buy certs which can be used to sign other certs, but they are
*very* expensive - hundreds of thousands of euro.
