A WIBNI (Wouldnt It Be Nice If) for Unix FS's for as long as I can reme= mber
(decades) but no one's ever done it.

Ways to get it done:
=C2=A0 Get it listed as a Google Summer Of Code project for FreeBSD, Or

=C2=A0 Get your employer to help pay for it, eg chip in with other BSD
=C2=A0 user companies to pay some money to FreeBSD Foundation, & get =C2=A0 them to pay for it to be developed.

=C2=A0 Or hire are an individual freelance BSD Consultant to do it,
=C2=A0 =C2=A0 =C2=A0 =C2=A0 There's a global index here http://be= rklix.com/consultants/

=C2=A0 & a mail list that's moderated jobs@freebsd

=C2=A0 Some author(s) of BSD FFS are on list fs@, Kirk is one name springs<= br> =C2=A0 to mind ? Some freelancers on fs@ I recall.

=C2=A0 IMO Would be a fun job if funded :-)
