By removing RR from their network would take more time and $$$ than BHN would wish to spend as well. Too far integrated and has been for too long. I'm just suprised that any MSO hasn't gone back to the @home era and just outsource the ISP completely- the same as Sprint did with Earthlink. Takes away total customer related problems - CSRs, Tech, etc. The Customer only deals with the ISP and not the telco provider.
