No, he means Phone -> Bluetooth -> N810 -> WiFi -> Laptop/etc

Yea, i know you can pair via bluetooth, but think about it. You have to pair all your devices with the phone, or you can just pair your n810 and create a hotspot that any device with WiFi can use. For example, if you and your three friends are on a trip, and you all want to use your laptops, you guys can't all connect to a single phone, even if all the laptops had bluetooth. So, you create a mobile WiFi hotspot and bang, instant internet.

I know for sure there is a linux app like this. In any case, it can be done. The IT is basically a full laptop, and internet connection sharing has been a norm for a long time. But I don't think we are going to see this built into the N900. This will have to come from a 3rd party. Nokia wants you to use their device, not another.
