Let me know how I can contribute the FFS implementation for NetBSD.
In case it helps for designing the API, here is the relevant man page:
http://netbsd.gw.com/cgi-bin/man-cgi?fss+.NONE+NetBSD-7.0.2

Basically, you find iterate on /dev/fss[0-9], open it cand call ioctl
FSSIOCGET to checkif it is already in use. Once you have an unused 
one, ioctl FSSIOCSET to cast the snapshot. It requires a backing store
file, which may be created by mktemp() and unlinked immediatly.
