RAID2 Over TCP/IP?

Cheeze asks: "I was wondering if there are any working implementations of RAID2 over TCP/IP. This would be a logical solution to high availability and data redundancy. The ability to have two identical mirrored separate machines with identical data stored on them would almost remove the risk of a hardware failure. I haven't heard or seen any documentation on this, but it should be relatively easily. On a high bandwidth (>=100Mbps) private switched network, there should be no problem with keeping the bandwidth up to par with the hard drive transfer speeds. a software solution would be practical, but a hardware solution would be optimal. Any ideas or possible future projects on this topic?" Is such a thing practicle, or even possible?
