Currently, I do the physical networking builds for a mental health company. We're already deploying 100 G-bit in these offices as primary connection trunks, because a lot of these services will be done remotely over video and audio.
I could open up a 20,000 user Camfrog Video Cluster chat room and could saturate a T-bit connection link just like that the second it's half-full. Have you ever used (let alone seen)a T-bit scale program before? Camfrog's been out for over a decade.
