In reply to Dave Evans.

Great idea Dave - that NSF "Grand Challenges" was sponsored by the CRA (Computing Research Association) in 2002 and CISCO was a strong participant there in Northern Virginia. I was one of three international invitees.

IoE also presents major security problems since in many cases simple "patching" will simply NOT be feasible as many of the "devices" will be based around firmware implementations, e.g. recent analysis of the open TELNET ports in major equipment such as routers, etc let alone many IoE type devices!. Incorporating crypto is also interesting, e.g. AES-256 for data encryption, ECC/RSA for key management, etc. but in many cases IoE may have little to no perfomance capacity to provide such crypto services even if TPM 1.2 chips are inserted - and that is NOT happening in many IoE type devices I have examined.

IoE can only succeed if citizens have full confidence and trust in any such structure. Remember "Unsafe at Any Speed" and Ralph Nader! The future relies and lives on the past!
