I've made a logo in Illustrator 10 using two large letters, turned into outlines and then overlapped so they intertwine. There's a slight gradient on the letters. The client wants a hint of a metallic look applied to it. None of the features in Illustrator seem to work. I imported it as a smart object into Photoshop CS2 and applied a slight emboss effect. I want to keep it as a vector. Is it possible to export to Illustrator as a smart object and keep the emboss effect? Or even better would be to save it in some vector format so I could work with it in InDesign CS2.

I'm getting confused by file formats and switching back and forth between programs. What's the best way to keep it as a vector illustration but keep the emboss effect while using it in InDesign or Illustrator? Is this even possible?
Any help would be greatly appreciated. Apologies for cross posting.
Thanks,
Jason
