He probably is trying to get around MMOPRG restrictions, in which many companies use technology to prevent players from using even virtual operating systems to run multiple versions of the program in order to prevent people from essentially breaking the game. It's insanely difficult for a person that plays a single character to find groups and stuff, when the majority of groups are run by a single person.
KMV switch will do the trick, as far as I know.
You'd think it would make playing MMORPG's better to try and limit people sandboxing multiple characters from the same computer, but it never worked, people have jobs and stuff and their own real life agenda, and it's just not practical to level up and gain important quest items by just randomly joining groups online. You end up spending hours looking for a group, then hope the groups lasts at least 2 hours. Not to mention there's the very real issue of getting keys and flags. (Keys and flags allow you to get to certain zones, or get farther along quests). If your join a guild that has all their keys and flags, it means they have to wait until several new guild members need keys, and then spend hours and days just getting flags and keys for the new members, when it's all trivial to the people running the keys & flags groups.
One day I joined a new guild, and one of the guild members took 5 of us new players, and spent 9 hour straight getting keys & flag. The guy that ran the group, didn't really get anything out of it, other than the drudgery of getting the new members keys & flags, so the guild could go on a particular raid, that was actually trival to the guild already, but was a fast way to equip new members.
I haven't played MMORPGs in 15 years, but I was addicted to Everquest for a couple years, around 2004-2006.
