Google to Branch into voIP?

Intriguing speculation that Google may be set to offer free voIP calls:

Mr Hewitt added that search results could be linked to its Net phone service, which allows customers to call a company by clicking on a link. Netimperative suggest that there are many ways for Google to extract value from this service. These range from charging users by the minute to employing their AdSense model, where companies pay the cost if a customer calls from a Google advert.

Organizing all the information in the world, indeed.
