Hola, Charles!
I have worked with live-availability XML feeds into a yacht charter company, displaying results in PHP and AJAX calls for a yahtzee game on my own website and more recently with updating a storm tracker tool in real-time. I have taken a quick look at the feed and the site with a similar result that you're looking for and I cannot foresee any problems. I would set it up so it's easy to change max results per page.
May I see the site you'd like to slot the results into please?
I'd love to chat more about the job.
