Manually Digitally Signing InfoPath 2007 Form

I have been trying to develop an InfoPath solution where I retrieve a users 
certificate from Active Directory and manually sign the form after asking for 
username and password. I found a good article dealing with this in InfoPath 
2003 using the old object model at 
http://msdn2.microsoft.com/en-us/library/bb608325(office.11).aspx but I want 
to use the new 2007 OM. I have been unable to find any documentation on how 
to override the wizard. I see no Add() method or Items properties in the 
SignedDataBlock class or Signature class. Has anyone looked into this or 
tried it in 2007 that can point me to the right direction. Much appreciated.
