bbr pool code is not stable.
Many bugs is fixed by zone117x.
Merge the newest code node-cryptonote-pool will help more pools online.
You want not stable, eh?
https://github.com/clintar/node-boolberry-poolIt has my attempt at making it workwith node-crytponote-pool. It works mostly, but I haven't figured out why the boolbd daemon rejects some blocks when testing on testnet (rejecting blocks seems pretty bad)
