Have you tried hastd? I believe at this time it only syncs to one remote 
node but Mikolaj Golub has documented how to build a "stacked" HAST setup 
out of 2x2 systems.  I think the plan is for hast to be able to use 
multiple nodes

Otherwise you could iscsi export files/volumes from each box (i.e. made 
with truncate or dd) and then use those into a zpool. I'm guessing that if 
you then nfs exported the file systems from that pool things could be a 
bit slow though :)
