"How'd you like to be able to make a bee line straight for the ketchup in the Mega Mart without having to walk down thirteen aisles first in a frustrating process of trial and error? Yeah, Nokia feels you, which is why it's working on developing an indoor positioning system that's robust enough to use -- and easy enough to set up -- to be commercialized. The company apparently already has some 40 buildings worldwide set up with trial systems, and it's working on a commercial trial with a Helsinki mall that'll go live later this year with the goal of figuring out how such a system could generate cold, hard cash. We wouldn't expect this to go big any time soon, but for what it's worth, there's talk of dropping a build of the client on Nokia's own Beta Labs at some point in the future."^^<http://www.w3.org/2001/XMLSchema#string>
