This is a very impressive demonstration of the new <!--bmlt_map--> shortcode. This page uses the UKNA settings (Settings ID 1303913596), the Na Minnesota settings (Settings ID 1313165300), the Tejas-Bluebonnet settings (Settings ID 1313164611), and the Greater New York Regional settings (Settings ID 1336917103).
Note that all four are completely independent of each other, and access vastly different servers, yet the page load is quite fast.
All of the settings should use the same theme, if they are to share a page.
