RSS feed - any duplicate content issues?

[Broadway]

I have used Google's AJAX RSS feed wizard to create their javascript code to paste into my html pages so I have a live feed from my blogspot blog.

I put this on all of the pages of my site.

I am assuming that Google will index the information it finds in the RSS feed when it visits? Right?

If so, could doing this create some sort of duplicate content issue?

1) Either between my blog and website.

2) Or else between the individual pages of my website?

In the past, the feed itself would sometimes show in the results, displacing the actual website page in the SERPs. That was bad news, because clicking on a direct link to an xml feed is a really bad user experience.

However, Google has addressed that issue quite well at this point, and things seems fine from that angle.

What are the benefits/problems of adding an RSS product feed to an e-commerce website? Positive thing or negative thing?
