With airlines preparing to unleash Internet access upon the skies, we're entering what Web evangelist Vint Cerf calls "a ticklish area." Confined airplane cabins has generated concern that flights are going to transform into nonstop phone discussions of the latest online porn releases — so much so that airlines are considering employing content filters and banning VOIP calls.

Right. As if frequent fliers don't already view air travel as a fantastic voyage into hell. There are screaming toddlers, 8-year-olds kicking your seat, and that damn guy who won't share the armrest. Phone calls might actually help muffle the din. No, any real road warrior's concern will be the new scramble for scarce power outlets. Using Wi-Fi nonstop will drain a laptop battery faster than just watching a porn video you downloaded before takeoff.
