Gateworking

Yeah, so, some of you may have heard already but I've volunteered to do a workshop at Thresholds on the Balon Matrix (specifically focusing on otherkin uses and mutations of it). One of the big ones that I know it can be used for is gateworking. I have some experience in that realm, more than enough to pull something off, but I'd like to expand my knowledge-base a bit before doing so in a workshop setting. So... ideas/techniques/theories of gateworking anyone feels like sharing? I have my own ideas, and I'm mining the lists for more info, but I'd really love it if we could get a decent discussion going here to help me prepare for the workshop.
