Xnormal seems to be exactly what I'm looking for. However I load my low, and the 10 objects in high mesh and everytime I try to export the map I run out of memory when the map is generating. I only have 2 gigs mem. Should that be enough? My high res objs also equal about 15 million poly's total. Is that too much?

Chances are you dont have enough RAM to render in one pass. You can however change the raycaster to "memory conservative". You can find that option in the normal maps dialog under ray caster. This could solve the problem.

The other method is to just add a few meshes at a time, lets say you add 5 out of 10, save that first render pass, do the same for remaining meshes and simply merge all of the resulting maps in photoshop.
