Just one of the myriad of security issues that we're grappling with are the various rights of the owner of the CPU, the *operator* of the CPU, and the owner of the *data*, each of whom may have a more or less legitimate say in what code actually gets executed. Far too many folks have already "solved" this problem incorrectly for me to believe that the "just a few months" solution you envisage will actually be correct. David Gillett
