It is nice to see that the Solo project is making progress.
Reading the article on NewsForge I think this would also be well suited to third world countries and also as a tool for NGO's doing aid work in these countries of following major disasters e.g. Indonesia. The ability to operate for long periods of time in areas with no power infrastructure would be extremely useful. Having tools like databases for tracking inventories, lost and found people, maps, contact lists, documentation and email via satelite phone could be very useful.
The A9home also has potential in this area, low power, replace the hard disk with a Flash drive and connect an alternative power source. The A9home is robust, lightweight, able to run suitable software, has low power requirements and is being developed by some very clever guys.
