NetBSD has the same (or similar) support for user-land access to raw SCSI
commands. xmcd uses this facility, as does my sdremap program, which I've
posted here previously.

Actually, I was thinking of something much more "high-level" than what
FreeBSD provides as a libscsi and scsi(8) ... The FreeBSD libscsi doesn't
look terribly useful itself ... It places a _lot_ of responsibility on
the calling application (much more than I would consider necessary), which
seems to defeat the purpose of a library.
