As a person who I suppose qualifies as both a female and a "circuit speaker" as well as a WordCamp organizer, I think that there's always a few things to think about. It's awesome as an organizer to be able to bring in some "big name" or well-traveled speakers from other cities into your WordCamp so that your local community can hear from some people they don't usually get to see at meetups. It's also awesome to hear from a wide variety of voices (both local and non-local) from all sorts of different backgrounds (not just gender), but difficult to do if the organizers don't know where to look. Always looking for help on that front! As far as wordpress.tv goes, it's a fine resource and all, but I think it's way more valuable to have a speaker there in person to be able to meet with, ask questions of, etc., so I am always going to be in favor of a speaker traveling and giving the same talk at multiple camps so that we can meet each other IRL more often. :)
