I'd be very happy for anyone who wants to push this stuff along to do so. Doug Gregor and I have proposed a couple of sessions for BoostCon where we get down and dirty with Boost code and C++0x features, to actually try to move some of these components along. So if those sessions are accepted, this will be very synergistic.
This may be a little off topic, but I am (along with a number of our students) trying building a set of C++0x libraries to experiment with the use of new language features and their impact library design. Part of this has been a small-adaptation of the MPL to variadic templates, which we're using to implement extended class and algorithm policies (along the lines Boost.Math). I think we have is an interesting start, but it's more like a first draft than anything else. Definitely still a learning processd, but like I said (and am now emphasizing) - experimental :) If anybody is interested, I would be more than happy to elaborate and/or open up the svn repo.
