We have had success with many species keeping them in socialized group.
But socialized is the key word : )
Multiptle males won't work well (or at all), and "bull" males often don't work well, as they hassle and/or constantly breed cagemates as well. We have seen that Bull male problem in Leopard Gecko groups as well.
Raising the group up from hatchlings is the best way to achieve a well socialized group. But just keeping three monitors together doesn't guarantee any success, there are certainly other subtleties to it.
That said, I feel a well socialized and cared for group is more mentally healthy than a single animal.
