I think Greg Lehey's work (vinum) could be used as part of a solution. Yes, one of the things on my wishlist is remote data replication. If you have any specific input, I'd be very interested. If you're at the AUUG winter conference in September, I'll be presenting a paper about vinum there. I'm currently at Compaq's Tandem Division in Austin, Texas, playing around with their XC machines (up to 6 Proliant boxes, each with up to 4 PPros, running UnixWare and pretending to be a single system). There's a lot of interesting stuff to be learnt there, too. If I ever get time, I might be interested in discussing the concept of clustering under FreeBSD. > The reason I ask is that I'm working for a geophysics data processing company, > and we have all the 32 & 64 node IBM SP2 boxes floating about.
