Baking maps for multiple objects in BI?

Are there any add-ons or scripts to bake maps for multiple objects in Blender Internal?

I saw the meltdown add-on for cycles which is a great time saver but I also would like to bake displacement maps for multiple objects in BI (from a high & low poly version of each object). Is there anything to speed up the process for the displacement maps on multiple objects in Blender Internal?

The Bake Tool is able to do this but are there any free options for baking multiple object jobs in BI? Thanks!
