Nothing should be dependent upon a particular person, device or storage medium. The village might be serviced by different people with different laptops each time. There are lots of people fulfilling this function, each with his/her area to service. The data from all these people only comes together at the central office. The laptop should only really be storing the data it picks up on its travels, not carrying a repository of millions of account holders. > Having > endusers with no proof of a transaction or ability to read their own > data I would have thought has the potential for a lot of social > issues, and potential non acceptance of the technology. Interesting point. To be honest I didn't think of that. > You may have already considered this though - it all comes down to the > data value.

But that's a hell of a lot of money for these people. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
