The ultimate eventuality is that the rewards from my zaps get split among my web of trust how I see fit, but the ideal WOT has not yet been specced.

In that case, I would still be for 1% going to the house, but go to .1% when the userbase increases 100x, and 0.01 at 10,000. And perhaps 1% going to a general pool that is split among arbitrary federations defined by network data visualizations that group WOT blobs.
