SL4A http://code.google.com/p/android-scripting/
you can script, yes write your own Python,shell even Perl, if you like.
it's been used for rockets, bot and who knows what see the page.
my self I added PY4A or python-for-android which let me use my favorite scripting language just like a linux machine.
only thing I fond bad was no direct sound card suport and some of the egg files did not install correctly.
See what you can do with it, clue Bluetooth suport is good.
