Change display of author information?

<aside class="post-meta">

already contains an LI for the author information. It generates something like this:

<li class="author"><a href="http://www.example.com/" title="Posts by Some Author" rel="author">Some Author</a></li>

can I swap that out entirely with a custom taxonomy? …via some filter I add to invoke my own code?

So just like I have a tags display in the aside, I’d have another taxonomy displayed.

I can write the code (I’ll borrow from the tags taxonomy) to pull from the new taxonomy, but I don’t know where to ‘splice’ it in via (I’m guessing) an add_filter() call??
