Anyone who'd like to help me put the sources to the NRL IPsec + IPv6 implementation up for FTP is invited to get in touch. It will runs on 4.4BSD machines (i.e. BSDI, NetBSD, FreeBSD, etc) and should be pretty portable to other similar Berkeley based machines.

What licensing requirements exist for people who might want to use this code in their products? In particular, does one need to obtain any licensing from RSA or Cylink?

No. It doesn't contain any public key stuff because it isn't the key management component. Its all available under a Berkeley style license, which permits unrestricted commercial use, and complies with RFC 1825, 1826, 1827, 1828 & 1829. Perry
