One of the proven benets of Network Coding (NC) is to achieve the data capacity for multicast networks. However, even though there has been a signicant amount of researchin this area, potentials demonstrators of these capabilities have not been widely shown or deployed. Thus, in this work we present a set of pre-computed ns-3 simulations to modelthe behaviour of Wurf.it, a Random Linear Network Coding (RLNC)-based reliable multicast solution for content distribution with cross-platform support. Wurf.it is based onKodo, a C++11 network coding library that provides the primitive encoding and decoding functionalities and a Simple COded REliability Protocol (SCORE), for erasure correctingpurposes in single-hop multicast networks. In this sense, the simulations are shown as part of the modeling required to evaluate the theoretical aspects for the perfomanceof Wurf.it. Therefore, our demonstrator consists of stored simulations with ns-3 in a laptop and a Wurf.it implementation within a WiFi network. For the implementation, a video content from a mobile camera is distributed with low delay using SCORE to a set of heterogenous receivers (e.g. dierent platforms). Use cases of Wurf.it are mild to highly crowdedscenarios, for example: sports stadiums, airports,service-waiting areas and museums
