Preparations on the Clients

The client side of patching is rather transparent. Actually no patching needs to be done at all on the clients.
All you have to do is to start vvvv.exe with the following Commandline Parameters:
vvvv.exe /client ServerIP
Example:
vvvv.exe /client 192.168.0.100
Assuming that 192.168.0.100 is the ip-address of your server. You'll see that vvvv is indeed in client-mode as it pops up a default patch with the title //CLIENT of 192.168.0.100
Note that the patch is locked by default.
