I would really love to see Native Client on Android as alternative to the dreaded Android NDK, and I really don't understand why this hasn't already happened, it's so incredibly obvious. Just give us the ability to deploy and run a PNaCl executable directly as normal Android application, and without all the Java and JNI shenanigans. The Pepper API has a lot more to offer than what's exposed through the NDK headers, and the SDK itself is much easier to get up and running then the NDK.
