Unfortunately there aren't any specialty labs that process Kodachrome. Everybody sent it to Dwayne's. So when Dwayne's quit, that was it for "official" processing anywhere.
But there is quite a bit of speculation that the remaining stocks of Kodachrome out there will come out of the woodwork in the future.
One guy at the Kodachrome Project has rescued a K-Lab machine and is actively attempting to resurrect it. http://www.kodachromeproject.com/forum/showthread.php?t=674
On the APUG site is a discussion, actually several discussions, about the chemistry requirements and tabletop processing. http://www.apug.org/forums/forum205/85529-kodachrome-type-film-formula.html Look toward the end of this thread.
Kodak processed Kodachrome by hand in the R&D labs, so it is certainly possible to do. But is it viable? Probably no less viable than someone pouring handmade wet-plates. People do it, but it isn't mainstream. The cost per image is either next to nothing if labor is left out, or it is astronomical if labor value is figured. I suspect tabletop Kodachrome processing will be the same way; thriving in the hobbyist world, and not worth the effort elsewhere.
