I'd like Option 1 out of those, but we all know Virgin Media won't implement what's best for their customers.
If they flicked the switch on DOCSIS 1.1 for *every* modem / STB, it'd flag up who uses the service illegally, who's using out of date equipment (STB broadband is SO 2001), and pave the way for a move to DOCSIS 2 so the network can finally be reasonably up to date!!
