I agree that for testing anything related to syncing or registration, it needs to be a local testbed. However, in this case, for people just trying out the new interface stuff, but not setting up the full testbed, KA Lite will seem completely broken (e.g. videos won't be downloadable). So, this isn't for purposes of testing this feature, it's for the pragmatic reason of not wanting to cause a basic test installation to totally break.
