Kademlia
did get traction; it is the protocol for BitTorrent's use of magnet links, trackerless torrents and other features.
It was not designed to act as a gossip-like overlay network for indexing content (similar to eDonkey/eMule), it was designed to act as an overlay network for identifying metadata of known keys stored in DHT.
The BitTorrent checklist is as follows:
1. [X] peer to peer file transfer
2. [X] Kademlia/magnet links for decentralized metadata
3. [X] Kademlia/peer exchange for decentralized tracking
4. [X] Gossip protocol for indexing magnet links
5. [X] integrated data proxying for anonymity/plausible deniability
Tribler solved step 4, OneSwarm and some others are trying to solve step 5.
We're indeed on the cusp of an impenetrable file sharing network.
