One approach I've used, instead of nofollow, is to place all the site's "utility" links in an iframe. That way, the urls are in the index, but there's only one url collecting and circulating PageRank, rather than having those links appear somewhere in every url on the website. This seems to me a good resolution, and I have seen no downside. It's just that the page layout needs to accomodate this arrangement.
