Thought I'd chuck in my 2 cents.
I only got ISBoxer a week ago, but I've been fairly successful so far. I'm boxing 4 dual ice spear totem witches at level 63. Currently able to farm merciless docks easily on them (have to watch out for yellow dogs, but that is more of a gear issue than anything, a couple of the witches die very quickly). The kill speed isn't too far off my LA mara, who I am also farming docks with. Haven't tried all 5 at the same time (in docks, I did in ledge while levelling), I think I will once I upgrade my computer though. Lightning arrow + 8 IS totems drops my FPS a lot.
A few things I've learnt:
Progression is annoying with the totem witches, so I did things the easy way; solo'd quests on the LA mara and just brought in the witches to pick up quest items so they could progress to the appropriate levelling area.
Before level 31 I was only boxing 3 (the other witch I levelled solo as my first character) and I found ice nova to be effective at lower levels. Just run the chars through an area until you get a nice group of mobs, aoe them down, rinse repeat. This didn't work so well in act 3 normal, where I did city of sarn until 29 with this method and then pub docks solo on each char till 31.
Syncing can be annoying (particularly in docks for some reason). I usually drop my totems and then swap between screens, moving all the characters close to each other so they're ready to move once everything's dead. The suggestion of running into walls / corners a lot is a good one, it works. If anyone has a better method I'd be very interested!
I'd say summoner would be effective (though perhaps taxing on performance, depending on your computer), but apart from these two builds I don't know if there are any other 'easy' builds to multibox. I found ranged builds easy to dualbox, but anything higher than that became a bit too frustrating for me.
