Great answer. The web issue is easier to mitigate if not fix completely since there is already a massive infrastructure for widespread, rapid browser updates, and crippling Javascript to eliminate attack vectors such as high-resolution timers is completely acceptable. The cloud/vm infrastructure is a massive problem though. It is 100% required that VMs be fully isolated. The entire infrastructure breaks down if they aren't.
