Is there any application that would benefit from remote RAM mirroring?

Question

I am thinking of a HW that would produce a copy of a local RAM directly in the RAM of a remote computer.The transmission method would ensure ultra low latency, low power consumption and high spectral efficiency.Would that scheme be suitable for any application?

The industry is going towards distributed memory at various levels of integration such as CXL, Infiniband, even Ethernet. I see a few papers on arXiv a week about distributed memory.

Maybe you could do mainframe-style lockstep computing with regular computers. Perhaps not true lockstep, but you could compare ram state at various checkpoints.
