in reply to Re^7: Reverse download protocols
in thread Reverse download protocols [solved]

I am not clear, because I don't know the solution, nor do I possess the abstract terminology. But I'm sure the problem is clearly stated to an open mind. I presented one minimum already. Are there others? And what are they?

And don't take my descriptions like "hash" literally. The fact that you haven't heard of something similar is no argument invalidating this problem whatsoever.

    I presented one minimum already.

    Actually you presented a maximum, an upper-bound.

    bw, bliako

      It's the absolute minimum - just one bit on the server downlink. I added one more edit to my question to make this crystal clear. I thought it was already.

        "I added one more edit to my question to make this crystal clear. I thought it was already."

        With respect the question posted was not at all clear in explaining the problem you are trying to solve, hence several confused people asking for clarification.
