-The FCC now requires all VoIP telecom providers terminating and originating 
to the PSTN to charge Universal Services Fund tax to end user customers.
-USF is 8.4% of revenue for VoIP Telco's.
-Last year USAC collected and dispersed seven BILLION dollars for libraries, 
rural health care centers, high cost rural Telco's and low income 
subscribers.
-The vast majority of funds go to rural Telco's.

I guess it was inevitable.
