Just wondering how the interactions between different coin nodes will work...  

e.g
If someone with a UtilityCoin wallet would like to send their UTIL coins via the XC XMixer service how does that work?  What journey do their coins take?  Has this stuff been worked out yet or is it still being thought about? Would that user have to use a decentralized exchange to convert their UTIL to XC, then send those coins, then convert back?
