Darkspeech and Hivemind

[Arravis]

Dark Speech (from Book of Vile Darkness) allows you to use the Words of Dark Unity power to create a hivemind. I have a vague memory of the rules for hivemind being updated somewhere after the Book of Vile Darkness was released. Does anyone know where such an update may be found? Thanks!

An additional question... can hivemind be used on a colony of mundane vermin (such as normal ants) to create sorcerers and such? I know the combat bonuses associated with hivemind would mean little, but the ability to create minor sorcerers is quite handy.

EDIT: Answered my own question by reading closer... since you're limited to hiveminds of only 100, you can never make a sorcerer, since it requires so many to do so.
