There's an interesting
article from Business 2.0 that suggests that Google is in position to offer ubiquitous WiFi to everyone. Becoming a giant ISP with WiFi service also would position them to overtake the whole telecom industry. Just think Goop or Gype instead of Skype. This is a bit of a wild speculation that probably won't pan out, but hey, if someone told you 15 years ago what Google would be doing today, you'd have had their head examined!
