I was under the impression that the link between those projects is distributed.net, as per the Moo! Wrapper website:
Note that we have intentionally left Distributed.net OGR-project out of scope since you can already join that project at Yoyo@Home.
I just went through distributed.net stats in detail and I think you are right.
dnetc@Home BOINC Team = Moo!Wapper (crunching RC-72 only)
yoyo@home BOINC wrapper Team = Yoyo@home (crunching OGR-28 only)
Thank you clarifying and based on this I would consider Moo!Wapper not useful either.
