Re: [nwcrg] [dtn] Network Coding and SATCOM

Hi Marie-Jo, all,

Following one of your request, we (Muriel, I and others) did the work in 
2013 to reference NC papers as the one below. It was expected to store 
(and update) the list over a wiki page. May be this will be a good thing 
for newcomers in the group to have this list.
