I think this would be a very good feature to have. Allowing one user to make multiple ratings on a product could lead to abuse, with users rating a product over and over again simply to drive up the average. The only way to stop it would be to allow only one rating of a product per user. I could see allowing the user to change the rating they gave initially - for example, if they continued to use the product and were ultimately unsatisfied with the product, or on the other hand if they discovered more uses for it and liked it better and wanted to raise their rating of it. But it seems to me that each user should be allowed only one rating of any product. Even if they are allowed to post multiple replies or reviews, they should still be allowed to have only one numerical rating for a product, which they can change if they one. If they are allowed to "vote" more than once on a product, by putting a second numerical rating in, that could be easily abused, to the point where the average rating becomes a meaningless number.
