POHMELFS (http://tservice.net.ru/~s0mbre/old/?section=projects&item=pohmelfs) is a network filesystem, thus not very similar to HAMMER (and the performance measurements vary a lot as Evgeniy Polyakov adds/removes features). A very interesting project anyway. You were probably thinking of btrfs (http://btrfs.wiki.kernel.org/index.php/Main_Page) on top of which Zach Brown and friends are building crfs (http://oss.oracle.com/projects/crfs/). These two seem to be moving in the direction Matt wants to take. Unfortunately I don't have the time to follow their development (only so many hours in a day). HTH, Aggelos
