Track and Trace

I have been asked to find out if it is possible to implement a Track and Trace system for parcels. See [login to view URL] the client wants to know if its possible to integrate (into Joomla) the Track and Trace feature shown on that site - so that his customers can enter the Royal Mail track and trace number exactly as on that site. When bidding please include in a PMB how you intend to achieve the result - I'm not looking for exact descriptions, but a rough idea so that I can see you are not a time waster who simply puts "this can be done" etc. Questions via PMB please Thanks
