Hmm. I did read three Austen novels, watched a few of the movie adaptions and know a little bit about her life (but not very much). At least I got that some of the stories (especially the vampire one) imitated her style quite strongly. And obviously, they toyed with her relationship to her family members, especially Cassandra. On the whole, however, there weren't enough allusions for me to recognize to find the vignettes terribly clever - which may of course be my lack of detailed knowledge. They seemed sort of random.
I have to add though that stories that play with some other work (or, in this case, biographical facts) are not my favourites and need to be better than stand-alone stories to impress me. I never read "Pride and Prejudice with zombies" as the first thing I thought when I saw it was: "Oh, well, someone's slapping some parody shock value on a very popular book for easy publicity." Maybe unfair, but you'd have to really convince me that it is worth picking up.
That said, the stories were okay to listen to. The vampire one worked best for me, perhaps because it created the society feeling I associate with Austen most strongly. The "Mermaid's tea party" impressed me a lot more though.
