[Wine] Tricking a process in WINE to think its on a certain IP address

[Steven Smith]

I want to make a process believe that its machine's IP address is whatever IP 
address I specify.  Do you have any ideas on how to do this?  I have been trying 
to go through the WINE source code, and have been looking in socket.c and 
iphlpapi_main.c, but I don't see any small number of places to change.

I have set up a bunch of virtual IP addresses, all associated with my machine. 
However, when I run a process under WINE on my machine, the process will use the 
main IP address of the machine.  What I want is for it to use one of the virtual 
IP addresses on the machine.

The big idea is that I want to run several copies of a Windows app on the same 
machine and make each copy think that it is running on a separate machine, each 
with its own IP address.  Although VMWare would make this possible, WINE is so 
much lighter and faster that I could have many more copies of WINE running than 
VMWare.

Thanks,
Steven
