heyo. i've been trying to avoid temp for a while but i feel like it's important to voice this: ddd (loadiine) dumps effectively destroy information, from an archival standpoint, since they make fake xmls that work just enough for a ppc-level loader.
when iosuhax go public, you'll pretty much want to redump everything. i imagine you can rework ddd dumps into installable format (i haven't tried, i've only installed my own disks), but this is just a pile of hacks compared to distributing a clean disk image or raw CDN contents.
also, distributing titlekeys is... less than ideal for a handful of reasons. it'd be wise to quit while you're ahead and try to avoid that on the wii u. distributing CDN contents with a titlekey can last forever... decades, centuries, whatever. just distributing a titlekey will stop working the instant Nintendo decides it will - directly or indirectly.
