Does ipsec-tools-0.7.2 support RFC 3554 (http://www.ietf.org/rfc/rfc3554.txt)?

This RFC is "On the Use of Stream Control Transmission Protocol (SCTP) with IPsec"
and basically says:

"SAs may have multiple associated source and destination  addresses. 
Thus an SA is identified by the extended triplet ({set of destination addresses},
SPI, Security Protocol).  A lookup in the Security Association Database (SADB)
using the triplet (Destination Address, SPI, Security Protocol), where Destination
Address is any of  the negotiated peer addresses, MUST return the same SA."

I am basically interested in knowing how this impacts SCTP multihoming w.r.t IPSec.
