Other than the BSD and Linux code base, which is designed for desktop and server systems, I like to get a list of suppliers providing embedded dual-stack solutions in case one wants to develop small clients or cost effective devices running IPv6.
IPv6 embedded stack suppliers that come to mind are Unicoi, Interpeak (now owned by Windriver), Treck and Interniche.
It will be good to know if there are any other ones that are available ?
