Well i would just like to thank you for actually considering it <img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" />.
I agree it would be a lot more work for you to initially maintaine ports since the engine is still undergoing quite some work.
Running through an emulator is nice since it would have it working, but it will be slow, upset a lot of people, will get more people to bug you to do a native one, etc etc.
Many thanks.
