It's not an impossible problem, but probably not solved yet, as there was little reason to solve it.

(Also, I wonder if most corps would even want it; real-time doesn't leave much space for fudging numbers and other shenanigans.)

Corporations are interesting beasts. They don't always want improvements. For instance, I've heard from people selling "cybersecurity" products to enterprises that customers worry that when a system points out a potential vulnerability and later it gets exploited, they can no longer tell regulators and insurers that they didn't know - so in the cost/benefit calculations, improved security competes against plausible deniability...
