There are a lot of apps that want to get the URL of a web page or some other piece of information from an app.

However, there's no generic functionality for this where apps can register that they support being sent information and other apps can just iterate through the list of registered apps.

Instead we end up with individual apps that want to patch other individual apps (normally the web browser).

anyone think we should have as service that support this so that

a) new apps can support the API
b) only a single patch has to be made against exisiting apps?
