        Indeed.  Somehow, I've failed to notice that.

        As per [1], it's quite the contrary: running Linux device
        drivers in user-space with Mach as the host kernel, while I'm
        suggesting running Linux as the host, and Mach in user-space.

        Somehow, I think that the latter would be a bit easier to
        achieve.

        ACK, thanks.
