How to run 2 ArmAs on the same PC

Need a crafted ws2_32.dll, which returns WSAHOST_NOT_FOUND in gethostbyname() for armedass.master.gamespy.com or armedass.available.gamespy.com if -nokey is given on the server (-host) command line.

Editor/Server:
\ArmA\arma.exe -window -nosplash -world=empty -nopause -host -nokey

Client:
\ArmA\arma.exe -window -nosplash -world=empty -nopause -connect=localhost

Will posting on OFPEC for beta, if someone interested, and on BI forum.
