1.  Introduction

   Guaranteeing both physical layer robustness and efficient usage of
   the radio resource has been in the core design of SATellite
   COMmunication (SATCOM) systems.  The trade-off often resided in how
   much redundancy a system adds to cope from link impairments, without
   reducing the good-put when the channel quality is high.  There is
   usually enough redundancy to guarantee a Quasi-Error Free
   transmission.  However, physical layer reliability mechanisms may not
   recover transmission losses (e.g. with a mobile user) and layer 2 (or
   above) re-transmissions induce 500 ms one-way delay with a
   geostationary satellite.  Further exploiting coding schemes at higher
   OSI-layers is an opportunity for releasing constraints on the
   physical layer in such cases and improving the performance of SATCOM
   systems.

   We have noticed an active research activity on coding and SATCOM in
   the past.  That being said, not much has actually made it to
   industrial developments.  In this context, this document aims at
