That's actually something I've been wanting to do for a while, I just haven't gotten around to it - basically a full "save state".

A workaround is to save something in the neighborhood to your favorites list, and then save the favorites list. This'll shoot you an email with a link that can restore that list, and you can send/forward that link to your friend. Once the list is loaded up, they can click on the go to marker button/graphic in the saved favorites list.
