scenario analysis

Hi,

I have just submitted an individual ID about location-based service scenario
for privacy consideration.
I warn you that it is rough :-) Any comments would be welcome.

Location-based Service Scenarios for Privacy Analysis
<draft-takahashi-spatial-privacy-scenario-00.txt>
Abstract
We propose a user scenario framework of location-based services to
 analyze security and privacy issues associated with the services.  The
framework is intended to cover the most of the location-based services
available today and in near future. There are many kinds of existing and
possible location-based services. Though, what is meant by location-
based service varies widely.  The framework gives people a common ground
from  where  discussion on the security and privacy issues can start.
