I want to be able to set it up so /home (and maybe other filesystems)

The environment should be mostly read-oriented, so I can live with
write-latent solutions as long as they handle the race/collision
gracefully (preferably by actually detecting and reporting it if they
can't avoid it).
isn't this just a description of a network filesytem... say NFS?
I am also interested in what you come up with, but haven't seen anything
that matchs. DRBD is not RW from both nodes.
I have also used RAID1 over AoE and iSCSI, but not sure if this would
help you at all either with only two nodes.
I was thinking just yesterday some sort of fuse filesystem is what we
need :)
