OpenStreetMap - Markers, labels and AJAX

Hi,

I want the following:
A fullscreen map, with OpenStreeMaps that can identify some markers around the world.

The complex part:
I have a PHP script that will feed and make all those markers appear on the map, so I can read from a database (I will do this loop).
I have another PHP file that will have to read to a database the status of each marker.
The webpage - with javascript/ajax has to make a remote call every 10 seconds like this:
mydomain.com/get_status.php?station=1 - each marker has an ID
mydomain.com/get_status.php?station=2
mydomain.com/get_status.php?station=3
The output will just be 0, 1 or 2
0 = Green Marker
1 = Yellow Marker
2 = Red Marker

So, the webpage must be only a Map - with markers that can change color every 10 seconds with an async ajax call.

When I MouseHover in the marker, it will show the NAME that I will define for that marker - in My PHP loop script.

I wold like a proof that you can do this job easily.
