That's probably true but don't forget that compatibility is a simple as
implementing a virtual machine. Given the connection to the hypervisor
technology mentioned in the article and the strong natural similarities
anyway between microkernels and hypervisors, it is not unthinkable that
one could provide compatability by executing legacy code in its own

The work by the various L4 groups at running whole Linux stacks on top
of various flavours of the L4 microkernel (including some of the newer
capability-based ones) demonstrates that the embedded space is not the
only possible application area, but merely the easiest one to target.
