I've always wondered what level of service a building owner could deliver if they bought a 100Mbps circuit from a tier 1 or tier 2 provider and split it through a building. What about splitting it through a block? Come to think of it, wouldn't that make them an ISP? You could even see a rise in private firms managing CPEs. So maybe this would be your best bet: either get a dedicated circuit into a PoP and pay for a cross-connect, or just subscribe to a lower bandwidth tier 1 line. This obviously depends on the availability of media in your area.
