Maps 0.5 will support this for the display_map parser function when using the OSM service. It’s possible I’ll also add support for display_point(s). Note that my work is just a link in a big chain here. Most effort to make this functionality possible is done by the guys doing the mapping server side work. Also, a lot of my code Maps is using for displaying static maps is heavily based on code from the SlippyMap extension by Ævar Arnfjörð Bjarmason and others.
Since there are no demo’s available anywhere yet, here you have some screenshots:

And yes, the zoom level is off, this is a bug that still needs to be fixed
