You would need to have mostly identical installs and then connect IP to IP which still works very well. If your locations are not too far apart, you would have great continuity. Game Ranger, despite many people asking, will not work with MVP as they did not add it in. Tunngle might, but one my one attempt to get it working, we could not. IP 2 IP works well though. Keep in mind this is only versus play. There is no option to play on the same side. With IP 2 IP play, your respective routers would need to be set up for the proper ports to be opened.
Setting sliders has to be done each game, unfortunately. Well, maybe someone knows a way around this, but I never knew of one. Also, the options you can supposedly set before you go into the game do not work either. Everything has to be set manually prior to each game.
I would be happy to give you our slider set we use for online play and the set up, but we also use classic pitching and we dumb the control down on the pitchers by 22 points each per pitch. We had to do this because, despite setting the sliders as low as possible, we were still getting very, very low scoring games. We eventually settled on this attribute edit that helped our games overall. The other great thing about classic pitching (no meter) is that it's not obtrusive on your screen while playing, plus your opponent can't tell if you hit the green zone (perfect pitch) area, but then again, neither can you.
Here's a recent series we are in that shows you that possibility in variety of game outcomes. Our 4 most recent games are attached. As you can see, we get pretty realistic pitch counts as well. Also, HR's are not crazy high. Triples are misrepresented because if you make a misplay in the outfield and the runner makes it to 3rd, the game doesn't count it as an error.
