OpenSSL and certificate revocation

[Richard]

Hi,

given the recent Comodo problem I was looking how OpenSSL handles
certificate revocation and found good information here:

 using OCSP http://etutorials.org/Programming/secure+programming/Chapter+10.+Public+Key+Infrastructure/10.12+Checking+Revocation+Status+via+OCSP+with+OpenSSL/
 using CRL http://etutorials.org/Programming/secure+programming/Chapter+10.+Public+Key+Infrastructure/10.10+Obtaining+Certificate+Revocation+Lists+with+OpenSSL/

Now thats a lot of code that must be implemented in the client - I am
wondering how many clients do in fact implement it?
