Check out ftp://research.att.com/dist/mab/cfs.announce for information
on obtaining CFS (and other files in that directory for papers on its
implementation, etc.).  You must be a resident of the US or Canada,
and must be mailing from a domain registered in the US or Canada, to
actually get the source code, because of ITAR restrictions.

According to the announcement, CFS hasn't yet been ported to NetBSD
per se, but since it was developed under SunOS and BSDI, the port
should presumably be easy.
