I agree I don't think you could do the c25k in your driveway per see but you can do sprints there and burn lost of lots calories, you can do walking lunges too, if your appartment has stairs go up and down those stairs, hey instant stair climber
... you can also put some good music and dance around your appartment for an hour... if you have a tv and dvd player you can do a dvd called "Walk away the pounds" by Leslie Sansone... the sky's the limit really, be imaginative, if there's a will there IS a way
...
Good luck and keep us posted on what you decide to do...
