Yahoo is considering giving users of Yahoo Messenger free access to tens of thousands of Wi-Fi hot spots worldwide so they can engage in instant messaging, including voice communications, while unplugged from their regular home or office Internet connection.

Yahoo recently polled users about a possible new service called Yahoo Messenger On-the-Road, but it has no "imminent plans" to provide this service, a Yahoo spokeswoman said on Wednesday.

A screen shot of a survey page was posted on Tuesday by the TechCrunch technology news blog, which covers "Web 2.0" companies and products.

The service would include fees for users who want to do more than instant messaging, such as browsing the Web, for US$7.95 per month or $2.95 for a two-hour connection, according to that survey page.

That Yahoo is mulling providing such a service isn't surprising, since Web portals are beginning to see Wi-Fi availability as an important promoter of Internet usage and thus of their services.

For example, this is a key reason for Google providing Wi-Fi services. Larry Page, Google's cofounder and president of products, said late last year about the company's Wi-Fi initiatives: "We're excited about expanding Internet access in general. We think that's really good for our business: As people have better access to the Internet, they do more searches and they use our services more."
