Everything here is my opinion. I do not speak for your employer.
ExchangeIt isn't so bad
Other programs, which earn their developers lots and lots of money, appear to do much worse even after years and years of effort.
Disclaimer: Okay, ExchangeIt 1.0 was kind of bad, but it was a 1.0. And okay, I'm still not sure why we decided to write a high-performance, high-reliability network server application in perl. But we actually made it work in the end. I'm kind of impressed.
Try Tailscale: mesh networking, centralized administration, WireGuard.
