You hear so much tough-talk and blustery grand-standing these days over data capping that it's hard to take any of it too seriously. A recent announcement by Comcast, however, is sending chills down the collective spine of Engadget (and seriously threatening to put a crunch on Thomas Ricker's... er, "movie" downloads). The company recently confirmed that it will begin capping its residential broadband service at 250GB per month (or roughly 124 SD movies) come October 1st, and could simply terminate customers who violate the cap more than twice. Of course, 250GB is a pretty large chunk of bandwidth, so you'll have to be entertaining some pretty hefty habits to break that bank. Then again, who likes the Man breathing down their pipeline?
