Thanks; it's a tool I regularly employ for vuln testing...

One comment, though - your custom registry entries: 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"MaxUserPort"=dword:0000fffe
"TcpTimedWaitDelay"=dword:0000001e

..are incomplete.
You should have one more value at that location:
"StrictTimeWaitSeqCheck"=dword:00000001

This is required for the TcpTimedWaitDelay value to be used.

Thanks for the suggestion.  This will be in the new release.  Here is
the CHANGELOG entry:

o Modified the mswine32/nmap_performance.reg Windows registry file to
  use an older and more compatable version.  It also now includes the
  value "StrictTimeWaitSeqCheck"=dword:00000001 , as suggested by Jim
  Harrison (jmharr(a)microsoft.com).  Without that latter value, the
  TcpTimedWaitDelay value apparently isn't checked.  Windows users
  should apply the new registry changes by clicking on the .reg file.
  Or do it manually as described in README-WIN32.  This file is also
  now available in the data directory at
  http://www.insecure.org/nmap/data/nmap_performance.reg

Cheers,
Fyodor
