Have a look at www.stratus.com for systems that also use hardware running in lock-step and that can run pretty much standard RedHat Linux.
The remote system in the case of the NonStop doesn't run in lock-step as far as I know. However, it uses the concept of an active and backup process. Context information has to be periodically synchronized between the active and the backup process by the developer, using features provided by the OS. There are some work being done for the Carrier Grade Linux specification to be able to support similar capability.
Stratus is quite widely used in the banking and telecommunications industries.
