Alas, I realize no such thing :-(  By "doing this", what do you mean?
Running an OCSP responder, or having a single-purpose cert?

Can you please expound a bit?

Maybe I'm reading the wrong doc.  @,

 http://www.idmanagement.gov/fpkipa/documents/CertCRLprofileForCP.pdf
 "X.509 Certificate and Certificate Revocation List (CRL) Extensions
  Worksheet 10: Certificate Profile for Delegated OCSP Responders"
Pg 51
