This was pretty exciting for me because I have been looking for this kind of technology for a while. Simply replicating our data is way too expensive for us. I found a number of commercial products that provide this type of solution but they are too expensive for our business model. So ... has anyone used this kind of technology with FreeBSD before? If there isn't an existing project out there, is there enough interest to start one? This paper gives a solid overview of the technology http://www-bcf.usc.edu/~dimakis/RC_Journal.pdf Andy
