If the "-d" option is going to be introduced, given that it is new behaviour for any tool on Solaris, it would be well worth the effort to go into some detail about how it interacts with all of the other options available for dlstat/flowstat. That said, I'm still getting the feeling that this is a solution looking for a problem but if others are happy... Darren
