    initial v1  
    1 I think you're misinterpreting the thesis. It says not to put a given share on the *same* server if it already exists there; not that upload or repair can't create shares that are duplicates of existing shares but on *different* servers that already have (other) shares. The latter is clearly necessary to achieve happiness. (Proof: suppose that one server has all shnums, and the remaining servers have annum 0.)
