Interesting. I had the impression it was just meant to be a repository for DOE-related numerical tools.

That's a shame, because having collections of useful tools like that makes it a lot easier to keep track of options.

Given that a few dozen US-based students attend ACTS every year, I hardly see how it is a game-changer w.r.t. the widespread acceptance of Elemental. I think the internet is doing just fine so far.
