Crunchgear has an essay on whether place-shifting technologis—specifically Slingbox—will undermine efforts to launch mobile TV services. Personally, I think the second option is the most likely argument against this—what they refer to as the death of net neutrality. Basically, the issue is data charges—the Slingbox service is free but the consumers have to pay data charges. While this is doable on an unlimited plan, those are expensive and if users start using too much “unlimited” will become “capped” pretty quickly. Eventually the data services will be good enough that it won’t matter, but for the next couple of years they’re going to be a signficant factor. Of course, if the telcos overprice their services too much the extra data charges may be a good trade-off…
