I just solved this with the help of Howard using the IExternalPage
The Item.page would extend the Basepage and implement the IExternalInterface.

Below a couple of snips that I use to get the job done:

.page
<static-binding name="onClick">popupDetails(this.href); return 
false;</static-binding>
This way I make sure the page pops in another window and NOT the current one!

.js:
/**
  * This function does the actual popup
  */
function popupDetails(pop2URL) {
  if (pop2URL) {
   aWindow = window.open(pop2URL, _detailWindowID, _popWindowProperties);
   aWindow.focus();
  }
}

Output .html:
...
<a href="/app?service=external/AveragePriceComposition&amp;sp=SobjectID" 
onClick="top.frmScripts.popupDetails(this.href); return false;">XXX</a>
...

Just thought I would share the resolution of my own efforts with the list.
