That's a good point

Again, this is about tastes! However, this is often true. Anyway, I
pretty much agree with this article :

That could be a way indeed!

Since I'm writting about dash, do you have an opinion about relocating
the read/peek method into the Chunk themselves ?
This seems more natural to read from a chunk than asking the Network
manager to read from a connection identified by a chunk.
This is something I was thinking about, but I have to read the code a
bit more to be sure it's doable.
