The last conversation I recall discussed the relative merits of post
codes as nodes vs. post codes as areas. Clearly OSM would prefer one
zip code schema for the planet, rather than one per country. For
context, consider this awesome 3 minute video by Derek Sivers. The
video is both informative and better than Cats!

XAPI will certainly be one way to access the data by bounding box.
You may choose to post-process the result, refine the query, or both.
Your query will depend on the implementation decided by the community.
As an alternative, you might consider setting up a local OSM spatial
database so that you can grow your own interesting queries.
