For any of you who have to work on a large number of Macs, either in a commercial or educational lab, we have some bad news.  Mike Bombich has officially retired NetRestore at version 3.4.  On his website (bombich.com) he states that the code was becoming to fragile and difficult to maintain and a complete re-write would have taken to much time.  If you are looking for an alternative he is suggesting that you can check out Deploy Studio, a freeware application that Mike says is a lot like how he wanted NetRestore 4 to be like.

But alas, it's not all bad news.  Mike assures us that Carbon Copy Cloner will continue to be developed and supported for the foreseeable future, and his boot picker is available again (on the Apple educational site).
