What I don't like about it is that there's an implicit hierarchy. Happiness is the key, not level of acomplishment as a slave.

Even if the hierarchy is centered around level of given control it's confusing. Why is forced transvestitism a less submissive act than foot worship? It's just inconsistant. It's one persons judgement on what that person feels is more submissive. It's hard to aply it on anyone else. If you are a foot fetishist, worshiping feet isn't particularly submissive is it? It also confuses masochism with submission.

I've got a million issues with this. Too many to mention.
