Except by april 1st they are supposed to HAVE to enable the firewire 
port for customers that request it. Comcast already briefly, and still 
do in some areas,  had this working. This enables you to get hdtv to 
your computer with out anything more than a firewire port and the 
requisite software, or with a digital vcr. Not sure about linux but 
there is at least one package in beta on windows that is working on 
this. While they will probably dick around and not get this working by 
April 1st or even if they do they will probably encrypt anything 
interesting, I still am nuturing hope.
