NAPs, or more correctly exchange points, are intended for itercarrier
operation. Enterprises are usually not allowed to connect to them.
So, if your organization is an enterprise, it's not a viable strategy.
Large hosting centers may be the functional equivalent of exchanges,
but they have an assortment of business models for who owns and
operates the servers.
Metropolitan area exchange points may be more relaxed in their rules.
