It totally depends on your expectation for the online play. Does it load? Yes. Can you both select characters? Yes. Can you make a kill as if you were in the same room? Yes. Can you play a 5 minute game? Not likely. Your best bet is to use the cheat code for 'you only live once'. A quick game will likely survive without desynching although many factors are involved in stability. But yes, you should try it. PM me and I'd tell you a bit more about plugins etc. Plus I'd be happy to play you.
