Is not having access to the xdata in native AutoCAD the primary concern ?
You can remove data from the components with GCE > Remove. You clients would then be able to view the models with having the OE installed.
Similaraly if you want regular 3D solids you could use SaveAs > CWEXPLODE. to my mind this would be quicker than exporting a .sat file and having to import it into a new model, unless I am missing something somewhere.
