A lot of what people are trying to protect is stores in the clear, though: I personally don't want people piking up my phone and stealing my address book and photos. Google's approach to this, a supported "jailbreak" (fastboot oem unlock) that formats the phone as it does its job, is tome the best solution, as it guts the incentives of people like comex to weaponize an exploit so well that any evil idiot can use it (in essence, the only people with the technology would be the "larger evil", as opposed to people like your nephew, ex-husband, or business rival).
