FreeS/WAN and NAT traversal patch

Has anyone used the NAT traversal patch (http://open-source.arkoon.net/freeswan.php#natt) with FreeS/WAN on SuSE? How well does it interoperate with NAT-T aware VPN client software e.g. SafeNet SoftRemote? How easy is it to incorporate this patch into the FreeS/WAN packages which ship with SuSE or would I be better off downloading Super FreeS/WAN (http://www.freeswan.ca/)? TIA Michael
