Although if you're only interested in small sections of data retrievable with an api map call then there is no reason you couldn't download the data [EMAIL PROTECTED] style, and import to postgis/shape and render using mapnik. This would all happen very quickly -- probably faster than the [EMAIL PROTECTED] equivalent (I haven't tested, so I couldn't guarantee that).
