    Just a nit, but the -sV scan was first available in nmap 2.53 not
    3.45. Up until 3.45 it was a secondary patch that needed to be
    applied.
    
    Not to denigrate all the incredibly cool work/improvements Fyodor has
    made on fingerprints in the latest versions, but... Jay (saurik)
    Freeman's nmap+V banner grab patch has been around since April 2000,
    a.k.a. Nmap 2.53.  -sV scans have been a staple for some security
    people for quite a while.
    
    I think I first heard about it at Fyodor's CanSecWest/core00
    presentation. Nmap 2.53+V was on the conference CD.
    
    It has just been finally recoded into c from c++ and put in the main
    distribution. It has been improved a little and yes it is still cool.
    
    Thank you, Fyodor for all the improvements, and Jay for the original
    prototype.
    
    cheers,
