I did it with multiple available tiles layers, just to see if I could
mix vector overlays on 900913 (Google/OSM Spherical Mercator) and
27700 (Ordnance Survey) baselayers.

I've not got very far wrt vector reprojection (mostly due to school
exams at the moment), but my current code with reprojections is here:
http://ge.pythonmoo.co.uk/maps/openlayers1.htm

In that example, the switch to OSGB is a little messy due to the
limited set of map scales available.
