Note that Matt's terminology is a little bit confusing. What he calls "mirroring" in HAMMER has nothing to do with RAID-1 (like gmirror), but it is rather a kind of replication. The "mirroring" feature allows replication between local and/or remote file systems. So, yes, it is intended to support clustering. Clustering and SSI is the main goal of DragonFly BSD, after all.

"Transparent" proxies seem to vary from the distortions of a funhouse mirror to barely translucent. I really, really dislike them when trying to figure out the corrective lenses needed with each of them. -- R. Kevin Oberman, Network Engineer
