However, as was pointed out then, apparently the encryption is to & from RIM's servers, not the recipient. So RIM have access to all the 'secret' messages. I expect GCHQ & the Met will make sure said systems are patched in to their surveillance programme in no time.

Thus, why not turn the Trusted Computing idea on its head? Simply make P2P public key cryptography available to your customers, and then bind your hands behind your back in an Odysseian fasion, using hardware means? Simply make it impossible for even yourself to circumvent the best cryptographic protocol you can invent, which you embed in your device before ever unveiling it, and then just live with it?

Unfortunately the present climate in England is such that I can't imagine such measures being anything but lauded.

Thus the need for credible precommitment, TC-style, at the hardware level..
