Balderdash!  Comcast is way behind the times. Two T-1 lines is not a "large
corporation" profile any more.  A T-1 is pretty puny nowadays.  Sure, Telcos
uses to make loads of money selling them to corporations (and still do) but
that is barely enough for home usage in the era of video.  I have a T-1 at
home and it is crappy most of the time for YouTube viewing.  I want more but
I live in the sticks and have to be satisfied with that.

My son has Comcast service at his mom's house and gets 16 meg download
service and that works pretty well for a teenager.  So, don't try to cry
poor mouth and say T-1 is big corporation stuff, Mr. Bowling.
