Concerning this point, you'll find a study that uses such scheme to 
rebuild lost chunks in "Robust streaming in delay tolerant networks": 
see http://oatao.univ-toulouse.fr/4111/
The erasure coding scheme is a specific elastic-window encoding scheme 
named Tetrys: see http://websites.isae.fr/tetrys/
