Ewan,

you may want to check the KAME project homepage (www.kame.net)
as both racoon and IPsec in FreeBSD are instances of their
IPv6/IPsec stack. Also, there is a very helpful mailing list,
snap-users@kame.net (www.kame.net/snap-users/).

SADs are in kernel, they can be manipulated with setkey(8), racoon or
any other application by means of libipsec.

Try http://www.kame.net/newsletter/20001119/

There is man page for SPD manipulation in ipsec_set_policy(3) but AFAIK
no for SAD manipulation. I would suggest looking at setkey source codes...
