AFAICT LOM only has three commands "PowerON", "PowerOFF", and "Reset", a far cry from what other BMC provide. It also requires another Mac in the same LAN to be the controller, and you cant use static IPs (which is pretty common for BMC VLANs).
Also it seems unsupported for the Mac Pro (2023) this thread is about?
They also won't provide any guarantees about components continuing to work, such as booting over thunderbolt that some clouds rely on. There's an awful lot of financial risk in providing MacOS as a service.
JetKVM is a remote KVM, not remote management. It does not have the same integration into the internals of a server.
