Okay, my merged-mining p2pool should now be reachable over the net as port 10332 at ot.knotwork.com
It is a p2pool set up as 100% commission to prevent it paying out any bitcoins. It merged-mines currently bitcoins, namecoins, devcoins, groupcoins, ixcoins, i0coins and coiledcoins.
Payouts will only be in devcoins. All the other types of coin will be sold, hopefully on my Open Transactions server
which functions as an exchange for many types of cryptocoins and other assets, and the proceeds used to pay out in DeVCoins.
Still to do is working out the details of exactly how to compute payouts, presumably after sale of the coins it should be possible to simply divide the number of devcoins by the number of shares it took in order to figure out how much each share ended up being worth.
Part of the purpose of this pool is to provide liquidity to the exchange by using everything other than devcoins to buy devcoins; part is to help keep up the value of devcoins by creating demand for them in terms of each of the other coin-types.
