Hi Ross,

This differs from the "ecosystem" models that Peerless, Intelepeer etc
offer where you can "peer" with their other customers - i.e., you're still
paying a per minute fee, you're just paying a slightly lower one.

It would have a flat rate cost per "dip" or even a flat membership fee
based on number of subscribers, instead of per-minute fees. But
monetization is for a later time.

This idea would not be a carrier - it would be a pure tandem, or "exchange
point for SIP", more like how internet exchange points operate. And it
would work across all carriers in the North American Numbering Plan. You
would not have to be a subscriber of a particular reseller/carrier.
