L4Linux is as real-time as any other virtualized Linux is, so yes, you
probably want to have real-time work separate from Linux.
L4Linux has a server interface which can be used to implement services.
Look at arch/l4/server for examples. It's a bit more complicated because
of the mixture of C and C++ but look at the input-srv file as the most
simple example.
