I met their first hire about two years ago, don't know if he's still there.
It would be fun to test on big iron, yes, but before doing that we'd need to write tests and test the tests on little iron to make it worthwhile. So when there arises a group in the community who wants to write scalability tests using, say, tclwebtest to run 'em, maybe my populate package to populate the database (it would be nice if folks added new options to that package, if anyone wants to, e-mail me!) it will be worth talking about.
