The MSN Search weblog has now announced that it is possible to use the system for tracking packages, or more specifically, packages from FedEx, DHL, UPS and USPS. Searchers can simply enter a tracking ID and some other tracking keywords and the Package Tracking Instant Answer will correctly construct the link. An example given is 'Where is UPS tracking number?' Additionally you could use the RSS feed for the search to really keep up to date on where your package has gone. Google has had this feature for a while now, although it doesn't have an option for DHL.
