Yes, there is geom_fox. The BUGS sections mentions:
The geom_fox framework has only seen light testing.  There definitely
     might be dragons here.

Do your own evaluation.

http://www.freebsd.org/cgi/man.cgi?query=geom_fox&sektion=4&manpath=FreeBSD+6.2-RELEASE

There is also gmultipath for 7-CURRENT. 7-CURRENT is not very
far from being released.

No, but it has GEOM which provides a generic framework
for creating volume management kernel modules. Several
modules for several tasks already exist. You can do
encryption, mirroring, stripping, RAID3 and many more.
It might cover your needs(or not).
