Getting ready for the next release of our front end this week, I believe I have all the data your looking for and would be happy to create a view for it. Would just need a little help putting together exactly what you are looking for....
I have active miners for a given p2pool block (addresses that were paid and how much)
I have node, pool, and global hashrate.
I think what you are looking for is the estimated hash rate per p2pool payout address based on the payment from the last block?
Yes, I believe that's what was shown on one of the tabs for p2pool.info.
Since the site is still down, and using Norgon's clone of it as a reference (even though it's not up-to-date yet... blockchain data from 6 months ago), you can check out the Active Users tab. That shows the data I'm talking about:
http://p2poolinfo.azurewebsites.net/Edit: from the disclaimer text on the clone site, it sounds a bit different. Based more on the valid shares submitted in the last 24 hours. It would essentially be the hashrate estimate corresponding to the current Payout Estimate shown on the various node UI's.
From the p2pool.info clone:
The following users / addresses have submitted at least 1 valid share in the past 24 hours. Note: Hashrates are very rough estimates based on the number of shares submitted in the past day. They may be off by 10-20% or more due to variance.
Yea, those numbers look a little fuzzy to me...
