Hmm. Haven't thought about it.

Having a scheme like "kemari:tcp:host:port" looks quite
challenging to me. We can of course add some quick hacks for it,
but adding a nice layered architecture should be more
appropriate. Similar to protocols and formats in block layer?
At the same time, I want to avoid anything over engineered.
