gmail contacts clone for wordpress MU

Looking for a clone of the contact manager from gmail. I want this clone to be a plugin for wordpress that will work on both a regular wordpress blog as well as wordpress MU. Plus these features: -ability to tag contacts using the native wordpress tags tables -separate text boxes for first name and last name (surname) -separate text boxes for city, state and zip -add country -add website -ability to sort by last name, city, state, first name, company -ability to add unlimited notes Setup/requirements -address info should be in it's own mysql table and work similarly to the wordpress postmeta table -Should mimic all of the ajax functionality of gmail's contacts interface -No html <table>'s should be used -separate css file -no inline styles -clean, annotated code following xhtml best practices -I must retain full ownership of code and have no copyright restrictions -should work like a regular wordpress plugin and require no extra work to install other than dropping it into the wp-content/plugins directory and activating it in the front end admin
