   Considering DTV's legal action against card hackers, trying to
   reverse engineer the actual RF would be a big mistake.

   Perhaps, however, HNS might be receptive to a LinuxDVB client for
   the DirecPC service. I asked a former HNS employee that question.
   He doubted we could reverse engineer the stream. 

   While it is true that the Windohs install of DPC drivers give you
   the keys for your data, who knows what else HNS did to encode the
   data. Probably nobody ever pumped the RF into a modem to see what
   showed up and how it compared to rekeyed data.

   DVB-IP EU maillist readers might be interested in the flipping
   though the SourceForge direcpc project. That being said I understood
   that when you sign up for DPC service you agree to only use HNS
   client software. Probably likewise with HNS hardware. There have
   also been court cases over DPC reverse engineering stunts.

   Bell ExpressVu uses runs a DirecPC service but I think they use
   DVB framing instead of DSS.
