Does ruby have a JIT compiler like Dalvik? If not, it's a no-go from a performance point of view. A more likely alternative then would be Lua (LuaJIT doesn't support ARM, but there's no reason it couldn't).

Dalvik was born without a JIT, and Ruby is getting some performance work.
If you mean for a fast switch, these scripting languages (except Lua) have abysmal performance - I refer specifically to Python and Ruby - and I'm perfectly aware of PyPy, Unladen Swallow, JRuby.
However, Google has enough engineers to reimplement a VM for another language again, like done for Dalvik.
