There is a site dedicated to active Daguerreo typists:
http://www.daguerre.org/
And here in the Netherlands a guy called Rinus Ortelee actually developed a hybrid process for making Daguerreo types, that even allows him to COPY Daguerreo types (so literally make new Daguerre types of old ones). This seems to be a unique feat up to now. He spend some 700 hours of research on this. There was a nice article about this in the Dutch Focus magazine of September 2007.
Here's a newsletter of that society with some english language reference to that:

And these are sites of Rinus showing some of his beautiful work:
