1. There are at least 13 pools but likely more due to private and unkown pools
2. Not yet, but there has been some interest in the idea

It does not exist for Monero but it would be a nice little project to create one. The main reason people don't seem to go for it is higher overhead. You have to run a full node, and you have to run what is essentially a second full node for the sharechain. With traditional stratum miners you just run a tiny mining program and have tiny bandwidth usage. The second reason, on Bitcoin in particular, is somewhat chicken-and-egg. Since not enough people use p2pool, it doesn't get blocks very often (takes days currently) and then miners using it get unhappy with the variance. I think p2pool is reasonably popular on some alts. 3. crypto-pool.fr is currently the largest known pool at 18.2% with "unknown" controlling 41.7% 4. Yes, an updates pie chart can be found here 5. Yes, same source as the previos question 6. If there is a formal procedure I am not aware of it. Reddit and Bitcointalk, IRC, Slack and other channels can be used to reach many Monero users quickly when needed.
