I'm working on something like this at the moment.  It will allow a sub-set
of data to be retrieved from within a pretty large bbox.  The data will be
from the most recent planet dump, but would be up-to-date enought for low
zoom tiles I think.

You can try it if you like:
wget
http://www.informationfreeway.org/api/0.4/node[place=city][bbox=-1,50,2,55]-O
data.osm

Once I have that working then I will start thinking about how to render
things for low zoom tiles.  Want to help?
