does it separate as process since Illustrator doesn't have a duo-tone color mode? if i export theembedded file back out, it it still duotone?
In regards to part two of your question, I think it depends on what file format you save it as. For example, if you save the AI file with the linked EPS-duotone as a PDF, I believe it converts it to CMYK (with no great degree of accuracy). I saved the AI file as an EPS and brought it into InDesign, and the Pantone colors I used in the original duotone showed up in my swatch palette, leading me to believe the duotone is intact. Visually it looks perfect on my monitor (I know, I know, that means diddly-squat). However, I do not have a Postscript printer and really don't feel like going thru the hassle of setting up test seps via Acrobat! G'luck!
