Applications of ham sandwich type results. References? A general principle?

Lately there has been a lot of interest on applications of the ham sandwich theorem and related results. There is a bunch of lecture notes and surveys that touch upon the subject. I dont know of any that touches the most recent developments and includes some applications to both combinatorial geometry and functional analysis. Is there a good reference in which they are summarized? The following is a list of the applications that I know of. Do you know of other applications? Heuristically, what is a good principle to recognize problems in which these theorems might lead to a solution?
