I have the p2pool up and running, the web page looks fine but when I attach a miner to it, I get nothing but errors about submitted share with hash greater than target.
I am using http:// rather than stratum+tcp://    Its acting almost like a clash of scrypt verses sha.

Any thoughts would be helpful.

Absolutely.  The p2pool code will attempt to prevent this by forcing a higher and higher difficulty onto miners on the node; however, it can be overridden by the miner providing it manually.
You can override the difficulty higher on a node but you can't force it lower than p2pool demands.
Correct.  The lowest you can set it is to the p2pool minimum share difficulty.  The problem with that approach is that with a giant hash rate, you're going to flood the share chain.  P2Pool will eventually adapt to the added hash rate by increasing the share minimum difficulty, but it still won't compensate if you're a majority of the pool's hash.  This will lead directly to what kano posited earlier: everyone else's shares will be orphaned if you've got >51% of the pool's total hash rate.

As a "nice actor" you would allow your node to dynamically adjust your share rate, or you would manually set it to something high enough not to cause the situation previously listed.

wouldn't the sharechain have the same problem as the BTC blockchain orphaning everyone else's blocks if > 51% and often if close to that?

So they're exploiting the fees now somehow in their latest attempt to attack decentralization? Testing out some changes now...

Orphan happend when bitcoin client ... use minimal or no fees protection.

I have conduce somes tests about that on Bitcoin XT (many orphan because of the fees strategies).
Return to Bitcoin Core with fixed (originals) fees ... and no more orphan.

hashing device is the same, HW errors are the sames, too.

Well, with the high centralisation of p2pool and now a very large percentage being one miner ...

I like how 75% of my shares were orphaned for 3 days before the 4PH jump then magically back to normal once it came online.

edit: looks like I spoke too soon, back to getting mostly orphaned shares.  Cry

Trying my hand at creating a pool. I have included a total of 5 coins that can be mined. btc, trc, xjo, mzc, and tit.
Site is a work in progress but the mining end of things works great so far. The front ends work but I am still editing them.

been away for sometime.

good to see p2p hitting blocks !

i'm updating mine to latest & will be back in action shortly.

does nmc merged mining still works ?

anyone having issues with s7 mining on p2p ? i am seeing much lower hashrates, abt 1 ths lesser GRRRRRRRRRRRRRRRRRRRRRRRR !

Now p2pool is displaying the following:

Warning: (from bitcoind) WARNING: abnormally high number of blocks generated, 48 blocks received in the last 4 hours (24 expected)

Some discussion on this on reddit: https://www.reddit.com/r/Bitcoin/comments/3ydwg2/warning_abnormally_high_number_of_blocks/
