If the values are you are looking for are fields on the user profile page, then they should be accessible now... As the documentation states, this utility:
"...does an AJAX call to grab /_layouts/userdisp.aspx?Force=True and "scrapes" the values from the page based on the internal field name (aka StaticName)."So take a look at the /_layouts/userdisp.aspx?Force=True and if the values you are looking for are displayed there, you can use the Internal field name to retrieve it.
