Forwarding a message from Adam Cheyer, who is hosting the presentation 
by Didier Guzzoni (another ex-VerticalNet colleague) at SRI this coming 
Wednesday 2004年09月08日 4pm in Menlo Park, CA.  (01)
The abstract (below) sounds really exciting ... I'm sure the talk (& 
demo?) will be even more so. Those who are in the San Francisco Bay Area 
may find this interesting enough to show up there.  (02)
Regards. -ppy
