what he fails to mention
Is that their tech is really squarely aimed at general file storage. No transactional stuff, nothing performance sensitive. Think file shares for end users and document storage that sort of thing. Nasuni reps are pretty up front about this (I talked with them a few months ago, one of my 3PAR reps went there). They seem to have pretty neat tech on paper, for IT organizations it is probably a decent fit for a lot of folks(if for nothing else a nice way of providing "WAN optimization" and portability for the data). For my workloads which have nothing to do with document storage(mostly application VMs and mysql databases) it's not useful in any capacity.
