Really? I look forward to seeing your description of the DHT algorithm 
in your thesis. My picture of DHTs was a little different...

Certainly.

Ok, a transclusion is a part of a document (with block-id X) that says

        "here, use 20 bytes of block Y offset 52"

i.e. it inCLUDES a part of another document, TRANScending the document 
boundaries.

Transclusion is as above. A Xu link is a document saying

        "The 20 bytes of block Y offset 52 are connected to 40 bytes of block 
Z, offset 40, because
        they talk about the same thing"
