we could also really use a code change to be able to set the custom difficulty to at least 5000 , instead of the 2000 it is currently. i know you can go in and modify the source yourself, but most people wouldnt/cant do that
Doesn't that already exist?
log in to p2pool and append /SHARECHAINTARGET+WORK_TARGET
e.g.
./cgminer -o something.pool.com:9332 -u mineruser/5000+16 -p none
that will return 5000 difficulty work to the share chain, and it will only serve 16 difficulty work (instead of "1")
