Droid fallback CJK and fontconfig?

Hi, As you probably know Google has released a Droid font set as part of its Android platform. While the font licensing is being clarified https://bugzilla.redhat.com/show_bug.cgi?id=472635 (Fedora packaging blocker) I've taken a quick look at the font files. The set includes a huge "Droid Sans Fallback" font with CJK coverage. Could the CJK folks take a look at it and tell me how this font should be treated: as Japanese-only, Chinese-only, Korean-only before/after current CJK defaults, etc? Han unification means someone will probably not be happy about it. I've uploaded preliminary droid packages there http://nim.fedorapeople.org/fontpackages/ so people can check them out.
