Well, a lot of brilliant inspectors might suspect that the rocker panels are part of the frame, they like to rust, but further under are two 'frame' rails and I've seen those rust too, where it comes together in the area between the front and rear doors.
The nice part is that if it's isolated, everything is fairly square, and it should be easy to clean up around the nasty spot and weld in some new metal. Then you can do some fancy undercoating work and maybe you could get it through for another year.
If getting it right means making a patchwork quilt out of the undercarriage, then it's probably not worth the effort, but if it's in one specific and concentrated spot, it's probably worth it to repair if you have some money into this car.
