It looks like it won't be long before VOIP, Skype and SightSpeed all can be used in more places. As HSUPA comes to be, with a more stable, and albeit, faster upload path, voice and video over a 3G connection will begin to emerge.
Already 3G users like me are running Truphone or Gizmo over a 3G connection on Nokia N95's here in the USA and in parts of the world where 3G exists. That changes the game. Now with devices like the Walking HotSpot from TapRoot Systems you can bridge the 3G phone to the portable 802.11 router and then have your own hot spot anywhere.
This is very useful for lighter applications as it removes the burden of paying for multiple accounts when you need to share that broadband.
