Thanks Justin. If I understand this correctly, Dalvik (amongst other things) will be fully open-sourced in very near future (HTC Dream should be released in a matter of weeks, if not days), soon thereafter someone who understand C will document its features and I can happily start developing Android apps using my own bizarre homemade compiler, without ever touching Java or C. That's great news, thanks.
