Hrsck I would be happy if some one published the early Tudor/Renaissance ruels that Stuart has been working on. 
Or maybe the Punic war rules.
Dan did some early renaissance rules for Italian Wars and War of the Roses. There was a non-Dan scenario for WOTR in Miniature Wargames last year or so.
The Punic Wars got an adaption in Wargames Soldiers & Strategy issue 82, think it was called Eagles Rampant, although a google for that might throw up a Napoleonic adaption someone did
There has been a range of articles in Wargames Soldiers and Strategy and Wargames Illustrated so checking through ye olde back issues you'll find the original material.
Some of the more popular and oft talked about adaptions were actually nothing to do with Dan so they won't be included. He posted clarifying all that sometime back.
I'm a huge fan of the system as Lion Rampant hooked me into Historical Wargaming so keep an eye out for when there's an article.
