Will the Burnin Mining rigs plug and play with MinePeon and the stock CG Miner or do we need a special version?
Yes, plug & play. There is additional option (voltage regulation) not yet supported by stock CG Miner, but you probably won't need to touch it at all.
Im pretty sure nearly all will need this feature because nearly all want to overclock. Its only possible to achieve high hashrates with overvolting...
