These CBS / CNN links sum it up nicely .. in a nutshell, there is a parallel universe out there with most non-gaming folks our age not even knowing it is there.
Also note that the predominant dev language used for highly scalable games is C++ (not an issue for OpenVMS)

Simply google "esports cheating" to see what a huge issue it is - on the client and the back end servers.

Part of the challenge facing some game designers is that they are still in the traditional (ok, I call it legacy) shared nothing, heavily distributed network architecture designs.
In addition, game developers need to address data consistency, availability, node mgmt., replication, HA, DR etc. in their application code, which makes the app developers role much more complex.
The world is rapidly moving towards a combo of regional based zones (dual sites in AP, NA, EMEA), with heavily centralized, high throughput, ultra low latency server designs in each of these zones.
With OpenVMS clusters, a great deal of the App developers tasks are simplified because a number of these developer activities (data consistency, node mgmt., replication, HA, etc.) are handled at the OS level. The developer can focus on code optimization, quality i.e. spend more time on their App which is where their core focus should be.

The concept to be addressed is "solution latency" which as you highlighted above, distance is only one component.

MAC server's are non-existent in enterprise DC's.

Graphics is not required for server side of eSports - its done on the client platform (in most online games anyway).
Back end server requirements are scalability, availability, security and high throughput, low latency interconnects for east-west traffic (server-to-server).

A biggie holding it back is lack of X86-64 server support and up-front licensing costs.
Both of which will hopefully be addressed soon.
