Hum... It's a cool concept, but I'm having trouble understanding how it "breaks" the link between the UTXOs.
What I'm trying to say is that in a regular coinjoin multiple parties are engaging, so there are many outputs and there is no clear way of linking who owns what.
However, in utxo-dealership, from what I could understand, there is just the buyer and the seller, so how could the "link" be broken (to provide privacy)?
