There's no currently active Sony or NEX hacks, so long dead I'm afraid.
And it isn't very useful. I don't think it went very far beyond the menu language hack.
There are much better areas to focus on if you're interested in camera hacks, like Magic Lantern, ML RAW and of course the GH1/GH2 with PTools. Also the Samsung NX1 with the Linux based hacks and high bitrates in H265.
