You could simply write your own Winlogon Notification Package - see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthn/security/winlogon_notification_packages.asp ("Winlogon Notification Packages"). It basically boils down to creating a DLL that has the following functionality

//Event handler for the Winlogon Logon event
VOID WLEventLogon (PWLX_NOTIFICATION_INFO pInfo)
{
    //Print the name of the handler to debug output.
    //You can replace this with more useful functionality.
    OutputDebugString (TEXT("NOTIFY:  Entering WLEventLogon.\r\n"));
}

//Event handler for the Winlogon Logoff event.
VOID WLEventLogoff (PWLX_NOTIFICATION_INFO pInfo)
{
    //Print the name of the handler to debug output.
    //You can replace this with more useful functionality.
    OutputDebugString (TEXT("NOTIFY:  Entering WLEventLogff.\r\n"));
}

and is registered with the system under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify

DllName = mynotifdll.dll
Logon = "WLEventLogon"
Logoff = "WLEventLogoff"

NOTE that the function names are arbitrary.
