Jace, you need to be more specific. There are about 6 ways to do what you described. Does it HAVE to be in the links section? If, so that blogroll doodad should do it. Otherwise, just pick a mechanism for calling the same links to multiple blogs. SSI, like georgeyw said, or even RSS. With like FeedForAll, you can create your own feed to include the links you want to display on the blogs. All of these are outside-the-post solutions, btw.
