In terms of original games, I'm told a lot of the Korean arcades ran unpatched XP machines connected to the internet for highscore sharing etc. needless to say, they didn't survive remote exploit attacks and ended up as zombie machines, probably lost forever.
I believe some of the MAME frontends support similar share scoring features based around hiscore.dat.
