As I've come to understand, this depends on what system is in use. In the Anglo-Saxon system, "free" market is everything. But in post Napoleon France for instance, it is considered a privilege to offer commercial services to the public, and one of the obligations that comes with that privilege, is to offer that commercial services to everyone who pays, without discrimination. I'm sure better suited people are around to explain these differences better then I can. If only revolutions wouldn't be in violation of law :) Paul -- God devised pigeons as a means of punishment for man. Probably after the destruction of Sodom and Gomorrha he wanted to make sure that people would never again feel comfortable enough in a city to repeat the sins committed there, and he created the pigeons as a means to make the city dwellers' lives more miserable, as a constant reminder of their past sins.

So they are little less than two cycles of Moore´s law away from MPEG4 HDTV. That would put it three years away but if the market is there, we´ll probably see it earlier. SDTV video-over-ip services should take off first though or we´ll end up with peer2peer set top boxes sharing premium channel services over broadband networks. Pete

Something I'm surprised no one has commented on considering the direction of this thread has been should ISPs be responsible for customer actions if they are not allowed to refuse service to customers? I'm surprised this hasn't come up since the latter half of the question also represented a fairly "popular" thread earlier. I'm interested in people's opinions.
