As mentioned, the App Store offers iLife 11 which does not contain iDVD or iWeb. I bought my new (2011) iMac a few weeks ago and it came with Snow Leopard and included both iDVD and iWeb, and my Lion 7.0 downloaded from the App Store a couple of weeks ago or so (and what a palaver that was!) included both, and both launch in Lion 7.1. Therefore, both were still current very recently.
But it looks like Apple have now dropped tham.
On the other hand, Apple Discussions still includes these two applications (whereas DVD Studio Pro was dropped from Apple Discussions a few weeks ago). And I have just noticed that Software Update includes updates for both of them so I am right now downloading them in case they too disappear! (Downloaded, and both launch OK (in Lion 7.1).
Why does Apple have to act so secretly, confusingly and without notice? "Computing for the rest of us" implies communication.
