For your information, Sun Microsystems has licensed SSH IPSEC technology (namely the SSH IKE toolkit). Sun plans to add the SSH IKE to future versions of Solaris. This means that future versions of Solaris will include full standard-compliant IPSEC, including IKE (the Internet Key Exchange). Solaris has the highest market share of the commercial Unix platforms. This means that most of the installed Unix workstations will likely contain SSH IPSEC technology in future.
