I have been usng sitewide links shamelessly for years and AFAIK there have been no ill effects.

I think if they are overdone in your backlink profile then I would be concerned. Diversity is the key to long life on the internet (read: link equity)
But I don't see any reason to be too concerned since half the blogs on this planet link in ridiculously long blogroll links, often 'incestuously to their own network websites, and don't seem to suffer many problems.

I believe if there are lots of sitewide links from footers or blogrolls, Google will only count the link as one, so you won't get any benefits from the other links, except maybe traffic.

As BeeDeeDubbleU indicated, I have never really seen any negative effects from such links. While site-wide links may be discounted somewhat, they still seem to carry more weight than a single link. I've seen such links used very effectively with sites large and small.

Site-wide links are always good and there is a valid reason behind it.
Most of the sites have inner pages with PR which means you are getting more weight/link juice.
It has always worked for me.
