You can download features within a boundary also with overpass api.

<query type="node">
  <has-kv k="place" v="city"/>
  <area-query ref="3600058974"/>
</query>
<print mode="body"/>

This will download all city nodes in the relation 3600058974.
see http://help.openstreetmap.org/questions/12554/is-there-a-web-service-exposed-to-get-all-cities-in-a-country

Just watch out, some Belgian node networks have parts in the
Netherlands or France.
