No one opens windows in these skyscrapers unless it's an emergency and a crane is outside waiting to hoist people away. Regarding cost, it's really not the cost of the ethernet or fiber. It's the cost of using the building owner's approved cable laying companies provided we can get permission to even run anything to the roof from the 15th floor. The GBS is something that would have been cool and superb accuracy really isn't necessary for the application, just reasonable accuracy and good consistency. I found out that the Cisco 7000 in that office has a very good clock, so we'll just hit enter on the tone and go from there.
