Lori - you might consider reposting this under "installations." It would probably get more views & responses.
There are engineered products manufactured for a floating application. There are any number of underlayment so that might provide a bit of give that might help you.
If you want solid wood with a bit of flex, I can think of a few ways of working what you will be nailing to. You could rip 3/4" plywood into 2"-3" stringers & set them 16" apart. This would approximate the feel of a floor on joist. You could put rubber cushion soles under sleepers & nail to them, have done this with in many gym & exercise rooms. Another thing would be rubber cushion soles under 1/2" ply, then staple & glue another layer of 1/2" ply on a 45 degree over & nail your flooring to it.
Probably a few other applications people can come with.
Good luck.
