I was thinking, how to "pull  back" small miners (all miners?) to P2Pool and this is some assumptions for new version of share chain:
- we have 3-5 separate share chains
- each chain has own min and max share power/diff (let say sc1 is from 1k to 10k, sc2 11k-100k, 101k-1M etc)
- each share have flag, that tells it is already used/paid or not
- when user find a share in one of lower chains, earlier share is marked as used and power of new share and old share is summarized (we can`t pay from lowest chain directly because of dust threshold) 
- once power or his share reach chain threshold he need to find one stronger share to bump it to higher chain till it reach one that can be paid
- each miner (payout address) starts in highest chain for 1-10 mins that node can recognize its hash rate and select proper chain/diff for him
- goal is, that every miner found share every 1/10 -1/2 block ETA time

Pros:
- share chain length can be reduced because of "summing" thing, every miner can/need have 2 active shares in each chain, no more need
- no more "wasted work" when block time exceeds share chain length - new share sum power of last share and current, oldest share can be removed from payout computations
- virtually any miner can mine
- big miners are in high power chains that small miners can easily participate in mining

Cons:
- more P2P data overhead (more chains to transmit)
- more CPU overhead: more data to analyze to create payout tx, more job to be done when share found


Sadly, I`m too small in Python tot try implement that.

@forrestv: can this work? B-)

I never sugar my coffee, drink it like a man!

Same, I was looking for deals but there wasn't any deal everything was way too expensive.

Here some questions:

a) Do you have a telephone number?
b) Your domain has been registered by a "Tom Hassel" in Norway. There is indeed one Tom Hassel in Norway. When contacted, he didn't know anything about cloudminr. So where could Tom Hassel be found?
c) You write in one post: "cloudminr.io is a Norwegian cloud mining company". However, there is no company registered by this name in Norway. Please explain.
d) The only company in Trondheim with any connection to "Cloud" is a company which is active in candy import.
e) You claim in the registry data that you are located at Olaf Tryggvasonsgate 2B in Trondheim. Nobody at this address knows anything about you or your operation. Please explain.
