I don't know about Carbon, but Sheepshaver started on the BeOS and one could run a full version of the MacOS up to about 8.1 along side BeOS with no real performance hit. For example, I used to run R5.03 on my PM9500/200MP and I could start up MacOS 8.1 and in a window or full screen. I used to use it to get a decent browser (NetPositive sucked badly by that point.) The MacOS was running as a process, and if it hung or crashed, you could kill it and restart it. This was all very similar to the way Classic worked in Mac OS X, save the way the apps ran in the same desktop as the main OS.

That's not quite right. Sheepshaver was approximately analogous to the classic mode where OS X booted a full version of Classic Mac OS in the background. I.e. a virtual machine like Sheepshaver Carbon was the old Mac OS Classic APIs ported to OSX. Classic support allowed you to run old binaries. Carbon APIs allowed you to port your classic apps easily-ishly.
