I'm inferring that the scheme being developed is something like the following: * At each village/town there is a single low-capability but functional pc. It has no reliable network. * The data owners want to be able to track e.g. taxes, accounts, small personal data. * They want to be able to use this data where *they* are, not where a specific reader device is. -Rob -- GPG key available at: <http://www.robertcollins.net/keys.txt>.
