What about getting the floor screened and refinished? Cheaper than getting it sanded and improves the value of the home. Plus then you know what finish is on it and can clean and protect appropriately.

Is it too worn for one of those minwax or rustoleum hardwood floor restoration products? I'd worry about the finish with this technique.

Found this link the other day and it's useful for figuring out unknown finishes so you can fix them: http://woodfloordoctor.com/_how_tos/articles/cleanpt2.shtml.
