Man, I hate that question, "Is it possible?".
Think like a programmer! Everything is possible! ;-)

The issue is not technical, but legal.
Google already has the routing logic built in but, if you are using
the free license, you can only use that routing information in
conjunction with a Google Map, and you may not save it and use it
elsewhere.

So, because of your requirement number 3, you might need to look into
other alternatives.
I don't know if the Premier license would allow you to do what you
want.
