As an experienced scientist myself, I can say there is plenty of scope for misunderstanding and misinterpretation, no matter how careful the original authors were. So I only hope that there will be some (maybe blinded) mechanism for communication between the original researchers and those replicating the published findings, in the event of the "usual" complications.
Also, who would do this replication? Would some of it be outsourced to academic labs with the requisite experience? Advanced findings often depend on advanced techniques. Outsourcing could be problematic, politically, since Big Shot No.1 might not be too interested in shooting down his pal, Alpha-MD-PhD.
