There are a bunch of different solutions to this problem being explored. Being able to give provide location context-specific services in your applications is something that I personally think is going to be a huge thing in the next few years.

My current company is actually providing developers with a service (currently Android only) to provide better location contexts in their apps.

If you're interested you can take a look at our homepage from my profile. We just launched our public beta this week so if this sort of thing interests you as an app developer, please check it out :)
