Yahoo, Hotmail contact importer

I want some one to develop web service for importing yahoo and hotmail address book given the user name and password. The web service shouldn't depend on any third party component in other word it should establish connection with mail provider and then extract the contact addresses from incoming response. Feel free to implement it with any language you prefer ? Java, .Net, PHP, ...etc? ( you will be responsible for deployment in PHP case ) ## Deliverables Please provide a working demo.
