Hey, speaking of logical volume management, what are the chances of ever seeing a software-based solution for striping, concatenating, and mirroring of filesystems? It needn't be full-blown RAID, but it sure would be nice to have some built-in fault tolerance. Have you seen the disk suite for Solaris 2.4? Something along those lines would be neat.
