Peter,

I presented the slides at 2004 November PKIX WG at IETF held in Washington
DC.

Subsequently I wrote a paper and presented it at NIST PKI Research
Conference.

I am happy to send those two collaterals to you or you are welcome to locate
them if they are posted on some web sites.

For those members of the class who weren't present at the time, could you
