Hi Marco,
thanks! did not know that ...

for people pointing to Google and there licenses: using opensource tools 
it's pretty easy to fire up your own tiling service (eg using TileCache, 
see www.tilecache.org) using your  own or 'open data'.
And there is always Openstreetmap (www.openstreetmap.org), which can be 
used. For example here in the netherlands this has a very good coverage, 
and there are even tiling services available for the openstreetmap data 
in our national projection system epsg:28992.

For a nice reference-layer in a map, I think the ability to use those 
services would be very very usefull.

So Jurgen if you have something to show ;-)   or need some help, please 
let us know.

Regards,

Richard Duivenvoorde
