Actually, in addition to this, it would be great if you could allow
the date to be specified in the path, i.e. allow us to make requests
in the form of http://www.nearmap.com/maps/<nmd>/<z>/<x>/<y>.jpg
(where <nmd> is the date)

The following related example of an "apache mod_rewrite instance" is
from http://wiki.openstreetmap.org/wiki/Nearmap#SlippyMap_Plugin_.28Method_2.2C_Using_hosted_URL_rewriting.29:

# Allows JOSM slippymap to browse the NearMap Aerial coverage 20091015
RewriteRule nearmap.aerial.slippymap.20091015/(.+)/(.+)/(.+).jpg
