Fair enough.

Beyond the basic question for a routing protocol (does it actually
route packets from the source to the destination?) the issue of most
critical importance is the manner in which it supports the economics
which drive the Internet.

The "desired" economic model for the Internet, the one that operators
have been pushing and enhancing since the dawn of the commercial
Internet, can be summarized as follows:

1. Maximize the ability to directly bill customers for resource consumption.
2. Maximize the resources available to sell.
3. Minimize the count and cost of overhead resources that aren't
attributable to specific customers.

We're here on RRG today because BGP falls short of this model in one
important respect: The routing table itself is very expensive to
maintain and operate yet those who consume it can't be directly billed
for their use.

For any of our solutions to proceed to implementation, we have to come
closer to the desired economic model. We have to come enough closer
than BGP does to merit the cost of change.

Any solutions which stray further from the desired economic model than
BGP does are simply non-starters. This includes Geoaggregation.
