Right, out of band management (by today's definition) means - assuming the chassis has power and network, you can manage the machines, this is primarily a hardware problem. As much as I root for Open Source software, I don't see how OSS can replace the AMT stack.
Our team has several racks of R&D servers 7500km away from the bulk of the team, and having OOB management is vital. Absolutely vital.

The claim that extant FLOSS solutions can stand in for AMT was false, but now the replies to that have set up a false dichotomy.
The opposite of a monstrously complicated, buggy proprietary interface with undocumented features is a compartmentalized, robust proprietary interface with a fully-documented public interface. "Sorry, we don't want to show you the design specs for our hardware." "Sorry, we don't want to show you the code for our secret sauce." That's fine. Just give the bits that can be flipped to slide all the way from maximum ease like your R&D use case to maximum lockdown like a Bitcoin-based service.
