Yes I did! Her husband really is named Joe and he's really an engineer just like on the show. I understand she consults on the show as well. I'm currently reading the book "Spook" by Mary Roach which is about the search for proof of life after death and communicating with the dead. It's very interesting and she writes with a humorous bent so it is not all science and stuffy. She has a section on mediums nad it seems that Alison has been to several leading research facilities and they believe she may be the real deal.
I bet you watch Ghost Whisperer too then! I know I do and while they are totally different in their view of the afterlife, it is still interesting to watch and think about. Have you seen Lisa Williams on Lifetime? She's really awesome!
