The last version of phplinks that I could find was from march 2003, and most of the domains that used to be devoted to phplinks are redirecting or show host pages. So it looks semi-abandoned.
And the active version of it that I looked at put ungodly big session ids on every link and every action, not necessarily ideal. But, like with links2, it might be simple to get it to print simple html urls to the page.
Since it's open source, and parts of it work, maybe it could be modifed to better fit the task?
This was the sample version of it running that I looked at...
