Again, how is it any different from you installing a tuner card onto your computer, recording a program onto your HDD/SSD and then streaming it using media center software. It's the same thing except it's off-site.
Getting all the broadcast TV channels in NYC has been all that great since 9/11, because the broadcast antenna was atop one of the towers. Some of the networks kept a spot on the Empire State building antenna, and quickly switched to it whereas others had given up their spot. Those had to lease a spot on antennas on Long Island or NJ, so areas of the city would get good reception on one and not the other depending on which antenna you lived closest to.
