These browser nowadays pretty good at handling bigger DOM. As recommended in
http://trac.openlayers.org/wiki/FrequentlyAskedQuestions, you should keep ~100-200 Features in vector layer. marker.moveTo() for number of markers within 100-200 should be OK.
>> this looks pretty easy, but for few number of markers, what if I have
more than one won't that be very consuming to the resources?!
from what I understand I will have to keep a reference of all markers used.

My example code:
function setLonLat(marker, lonlat) {
var newPx = map.getLayerPxFromLonLat(newLonLat);
marker.moveTo(newPx);

var marker = new OpenLayers.Marker(new OpenLayers.LonLat(102.2168, 3.09185), new OpenLayers.Icon());
var markers = new OpenLayers.Layer.Markers( "Markers" );
markers.addMarker(marker);
map.addLayer(markers);
// To move the marker
var newLonLat = new OpenLayers.LonLat(102.1399, 5.72857);
setLonLat(marker, newLonLat);

Hi All,
I'm thinking of building a website that has openstreetmaps integrated to it, I need to show my position on the map each time I send my coordinates from my mobile, is there a way to show this without refreshing the page? like adding a layer that shows a pointer to some coordinates and can be refreshed without refreshing the whole page or map?
