Random .sigs

Here’s a question for the masses: is there some way to have random rotating signatures in MT-Newswatcher on Mac OS X? I used to have it doing that, but I was using this super kludgy extension that was an Internet Config hack such that every time IC asked for the signature, it would give a different answer from this pool of text files, one file per sig. I’d love to see this functionality one day roll into the actual program. It’s, like, not that radical or uncommon to want to do this.
