For all the occasional internet shortcomings he might have, Mike made on FB a very tasteful post about the show and his past in DT, saying only nice things about the band and how grateful he was to relive those memories.
I think too that an eventual reunion, although very unlikely (and Mike himself acknowledges that), would pass through Mangini leaving of his own accord and desire, and JP sitting down with the other DT guys asking "So, guys, what do we do? do you think you can sit down in a room with him and see if it would work again?"
