I bought a couple of skeins of 100% bamboo yarn and had planned on socks, but the yarn is too limp for that. I ended up making the Branching Out scarf with it and it is wonderfully soft. I tried blocking it the way I do wool by soaking it and pinning it out to dry and it was just as limp when unpinned as when I started.
I don't know if there is a successful way to block bamboo.
