Thanx, also to pjd's answer. That gives some nice insight already. Great work! HAST could in fact change radically the way of using block devices and distributing mass storage. I look forward to testing it first on a few vboxes and shortly thereafter on real machines. 

Really curious on how several things are implemented, e.g. performance / latency / fail / sync issues (what happens for example when a big huge file is written locally on a very fast primary, and there is not enough ram to buffer it before sending it to a secondary.. etc, scenarios like that). 

And how well it will do with ZFS too: although ZFS has its 'own' HAST via send/recv (and besides might get its own implementation for some sort of 'streaming' send/recv..) it is also true that it'd allow for some great flexibility in creating primary/secondary volumes (zvols). Just imagining a scenario with sparse zvols and HAST disting them around.. ok ok I stop here :-)
