Where would a Distributed Hash Table be used in place of BitTorrent?
===

The lack of recent research into the field of [DHT][1]s in comparison to [BitTorrent][2] ([Tribler][3] being the most significant research project) has lead me to wonder about the usage of DHTs. 

Both BitTorrent and Distributed Hash Tables provide a method for distributing content among peers using a key-value like datastore. What are the use cases where a DHT would be more applicable than using BitTorrent?
