Andrew recently asked Evgeniy if his DST was ready for merging; to which Evgeniy basically said yes: http://lkml.org/lkml/2007/10/27/54 It would be great if DST could be merged; whereby addressing the fact that NBD is lacking for net-vm. If DST were scrutinized in the context of net-vm it should help it get the review that is needed for merging.
