Sorry, looks like test.ckan.org being down right now or pointing to
the wrong place, but it should be back shortly

Nothing much really, it's mostly up to the tiles provider. We are
using Mapquest Open [1], as it is based on Open Street Map and allows
direct access to the tiles (as opposed to e.g. Google which forces you
to use their javascript API), in our case from OpenLayers.
The only other freely available option comparable in terms of direct
access to tiles that I know of is Bing Maps.

I see your point. (just make it clear, the area you selected and the
one you see after the search is the same one). The only solution I can
think of is passing the current extent as a parameter when doing the
search, so the result page can adjust it. If it is not present, just
fit to the are as now.

It is definitely possible but I wouldn't like to add more complexity
to it and just focus to a single way to search (the current bbox based
one or a different one)
