I > don't think that's an unreasonable position to start. Part of that is getting the Advanced Socket API recognised by POSIX. As a developer it is a right pain in the backside that it isn't and you have to do different magic incantations to make the Advanced Socket API visible on different platforms. Making "socket(AF_INET,...)" fail would also be a interesting idea. You can talk to IPv4 nodes over socket(AF_INET6, ...) using mapped addresses. A boring but useful Google Code project would be to go through the OSS that is still IPv4 only and add IPv6 support. Adding fast failover to the next address would also be useful at the same time. Pick a something like FreeBSD ports and bring all current ports up to scratch. > -- > james woodyatt <jhw@nestlabs.com> > Nest Labs, Communications Engineering > -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
