I have two computers that I multibox 5 toons on and I created a point-to-point firewire network between the two of them.
All of the software tools I use for syncronization run on this secondary, dedicated high speed low-latency network.
I use Kavoom KM, KeyClone and windows file sharing, they're each setup to use the firewire networking, so only 'game' packets are transmitted over ethernet and syncronization chatter isn't.
Normal Ethernet Network (linksys router with dd-wrt) = 192.168.1.201 and 192.168.1.202
Firewire Network = 10.0.0.1 and 10.0.0.2
Then I got a program off of curse gaming called 'FasterPing' that tweaks your registry settings to improve game performance.
(Improves how 'small' packets are sent.)
It works like a charm. All 5 of my clients are reporting under 50ms lag.
There is a trick you have to do to get keyclone to work on the secondary IP address, you have to change the order of network interfaces in 'Advanced' settings of network settings.
You also have to edit C:\Windows\System32\Drivers\Etc\hosts and lmhosts.sam to put static ip mappings to the host names.
