Media distribution traffic dominates the internet traffic today. Additionally the majority of users seem to adopt free and open media distribution services as YouTube and peer to peer systems.

Social networks look like a promising environment able to bridge the gap between these two worlds. On the other hand such an attempt raises many research challenges that we first have to address.
