Don't get your hopes up about TCP Fast Open just yet.
Early testing shows it has issues in some situations (https://lists.bufferbloat.net/pipermail/cerowrt-devel/2012-December/...)

Although this is an Internet-wide feature (if it makes it) but implementations only exist in Linux - (3.6 client and 3.7 server)
