Great! What distribution are you using? I would like to test converted my
Debian packages to RPMs if you're interested in testing.

That's correct.  Unless you need to do something with your configuration to get
hamachi to work at all then these patches should remove the need to do the old
tweaking.  Relevant explanations:

/etc/hosts:
The patch does a test to see if the loopback IP is returned for
gethostbyname("your_computer_name") and if this would be the case then it
returns instead the list of IP addresses corresponding to all of the "local" IP
addresses.  This list is returned based on the routing priority, as it is
according to the documentation and under all my Windows testing.  So, provided
that your hamachi VPN connection has the highest routing priority then that is
the IP address that gets returned to the game (you can check this in-game by
going to the network settings).

route 255.255.255.255:
I never saw this configuration actually work; however, my understanding of the
code and this option is that this change allows the game to send to the
broadcast address as if it is any old IP.  This set of patches should not
require such a change as it is setup to do broadcasting "properly."
