So, I wanted to report that this works great.  Nesting inside my coarser run, interpolating the initial condition and the boundary conditions onto the smaller nest, and just running, seems steady to the large scale (mode-1 internal tide) forcing for at least two tidal cycles.  No need for a sponge.

Thanks a lot for the suggestions.  Cheers,  Jody
