Is it kind of like the Sun Java or Mozilla licenses? Last I checked, which has been while now, it was binary-only download; built for only a few specific RH kernels. Checking now, it's up on developerworks with a BSD license, but I don't actually see any released files.

Cluster extensions for LVM. Given shared storage, a few configs, and running clvmd, you can activate LVs on multiple machines at once. This is great for GFS, where it replaces the gfs "pools". http://sources.redhat.com/cluster/ As I said, not all of the right bits seem to be in place yet. But I expect RHE4 to be very capable in this department. -- Garrick Staples, Linux/HPCC Administrator University of Southern California
