Both of them are interesting technologies.   

Of the two dtrace is the more likely candidate to have immediate 
value to typical embedded developers ... who doesn't want to 
know more about their system.  We're looking at it and how it 
fits in to the system profiler/instrumented kernel story and 
hopefully will have something more to say shortly (weeks not
months).

The ZFS capabilities are nice, but are much more server oriented
rather than being targetted at embedded systems ... which may
have the same block storage capacity, but are still small systems
from a memory perspective (ie your in-memory data structure 
selection still matters a lot).

One project which has been worked on a bit internally here has been
a port of FUSE (fuse.sourceforge.net) to Neutrino (which already has
filesystems in "userspace").  There is a ZFS port to FUSE, but I
don't think that it has been up and running yet.

Hope this helps,
 Thomas
