This past week has seen two major service announcements in IP voice and video communication that challenge the telcos. Internet big boy Google rolled out voice and video chat integrated with its Gmail webmail service, and FreeRinger announced PC-to-phone calls in partnership with GTalk2VoIP and Talkster. Both services are free, ad supported and share no revenue with telcos like AT&T, Verizon or Comcast.

Comcast has announced that beginning October 1, they will institute a 250 GB monthly bandwidth cap for their high speed Internet customers. If you're a customer, you can now look forward to monitoring your bandwidth usage the way you do with cell phone minutes. Comcast insists the bandwidth cap is consistent with previous policies, and the publication of specific numbers is an attempt to clarify the policy for customers.
