You can modify the projection in which a map is displayed already.
An example is available at
http://www.openlayers.org/dev/examples/freemap.html :
map = new OpenLayers.Map( $('map'), {maxExtent: new
OpenLayers.Bounds(33861, 717605, 330846, 1019656), maxResolution:
296985/1024, projection:"EPSG:2805" } );
var basemap = new OpenLayers.Layer.WMS( "Boston",
"http://boston.freemap.in/cgi-bin/mapserv?",
{map: '/www/freemap.in/boston/map/mass.map', layers:
'border,water,roads', format: 'png'} );
Bounds is the extent in the units that the projection determines:
maxResolution is degrees/pixel at the most zoomed out.
If there is more that OpenLayers needs to support in this regard, please
let me know.
