It looks promising, specially the GNUdroid component (I haven't found any proper instructions in my 2-minute internet stroll), but what they are doing would let Java apps work, but not apps coded with the NDK (such as many OpenGL games); with libhybris you can pretty much get any app to work (how hard that is remains to be seen, haven't really given libhybris a good look yet) as you can wrap shared objects with it and obscure libraries shipped with working NDK code can be executed against a GLIBC/EGLIBC system.
