The idea behind L4Linux is to run native Linux applications, so hello
world in L4Linux works just as the version you would write in your
local Linux.

Running an application that communicates with both L4 and Linux is a
bit more involved. L4Linux applications don't talk to L4 apps
directly. The L4Linux kernel is an L4 app though, so it can do this
talking for you. The missing link then is to write a Linux device
driver that allows your Linux program to talk to the L4Linux kernel,
which then in turn communicates with an external L4 application.
