Works great here!!!
I'm running on Waninkoko v2 and no trouble installing the dev_blind or openPS3ftp packages. I already had blackbox however the tutorial clearly states you NEED openPS3ftp, blackbox probably can't see the dev_blind folder so anyone having this problem, do exactly as the tutorial says.
Took a few restarts for it to work, however when I did finally get it working I had also added secondary dns on the PS3 as my routers ip (The one used when configuring/entering the interface of the router), maybe this was a step I missed, not sure, but it's working a treat.
Great work devs, thank you!!
