Wroclaw University of Technology (Poland).
We have this program, called "Visiting Professors", and from time to time some big fish is coming for a week or so, and giving out series of lectures in their field of study. It's also arranged in that way, that after every lecture there is about 30 minutes for asking public questions, and another 30 minutes to talk to the lecturer in private (yes, even as engineer course student, I was able to reach him and engage in 5 minute conversation, of course after waiting for every fanboy to make a photo with him and his nobel medal).

As for your post, this picture sums up the changes they are going to make. You are right, the orginal model of Kilogram, over the time of ~130 years, lost around few hundreds of miligrams, caused by radiation, cleaning, flawed methods of storage in early XX century and so on.

They've waited this long for two reasons:
1) They wanted for every major country, to have the apparatus that would be able to recreate every defining experiment with sufficient uncertainity
2) USA is as always, holding things up, by not adapting SI system by law (almost whole hall bursted out in laugh when this was mentioned).

As for tinfoil posting, I've learned to ignore it. These changes are made in such way, that you can recreate them on almost every university. And universal constants are able to be measured (well, to some extent) in very basic environments, so there is no place to argue.
