Ok -- a simple rotating banner script is what I even started with but my requirements got a whole lot bigger. Phpads has been working fine and it is keeping up with the speed of the board. Of course I have it running on a dedicated server also now. As a result remote invocation is my only option regardless but with it being on its own server then it can handle the pace of the board. They are not that far from releasing a new version from what I can tell. I am still using one that is around a year old and plan on upgrading it once I get one of my old servers rebuilt.
Am in the middle of our high season so the forums are going bananas and that has been keeping me busy enough the way it is. One of these days I will get around to upgrading the forum software.
