Sorry if you viewed my answer disrespectful. It was not my intention. 
Any contribution is appreciated, and while your findings are currently a 
bit hard to explain, they are useful. But asking developers to react 
directly on even a small proportion of the mailing list mails would 
effectly shut down VirtualBox development. Which neither of us wants. So 
I've asked for a little patience, not more.

So we both agree on the status of the hack. Have you tried the latest 
SVN code? As I said it may improve network performance in general (and 
NAT too). So feedback on that would be most welcome.
