I only commented sparely, because I am all too given to bloviation =p
I do like very much that you intend to mitigate stake with rep. I reckon it's a great step forward, as rep is community vetting (which will matter much more when bots are incapable of influencing it).
I am not a coder, and much of the guts of the system you are making are above my pay grade. I am also mentally incapable of parsing further the rep/stake weighting of VP, at least until I see a particular implementation.
I'll look forward to further development. I am greatly interested!
