Dalvik seems really interesting to me, even out of the Android platform... It is really an intermediate way between simple VM-based applications and compiled ones.
So I certainly would want it as a standalone technology which would be used as a production platform.
My request now would be to have OSGI running on it.. There is an interesting article about this I enjoy you to read.
A last news : NDK is avaliable to download. NDK means Native Development Toolkit and enables to use C/C++ code with the Dalvik virtual machine.
