have to say, p2pool will run best with http protocoll, however , - bfgminer seems to run stable on stratum+tcp .
ccminer for example does not with stratum, seems to be a problem between stratum protocoll p2pool and stratum protocoll ccminer. (use http for ccminer)

to make sure you are running smooth, connect to

http://htmlhigh5.com:65050/ -u youraddress -p anything

you can set switches to your address for fixed lower/or higher diff

sample for 500kh/s :
http://htmlhigh5.com:65050/ -u youraddress/0.005+0.0003 -p anything

0.005 would be the actual share height you need to get a share accounted,
0.0003 is the pseudo share height to check the hashing speed)

math samples:
multiply the sharediff with 65535 to see it like other pools show it ...
from example above:
Accounted shares: ~ diff 393 (0.005)
Pseudo shares: ~ diff 20        (0.0003)

so for a diff of 256 it would be 0.0039 etc ....
