Someone correct me if I'm wrong, but the raison d'être of the Illumos kernel (upon which OpenIndiana is based) has always been the cloud, with Nexenta and Joyent (SmartOS) doing the heavy lifting. They're basically ZFS/DTrace machines. I've played with OpenIndiana too but it didn't fill any real use case for me, at least locally. The userspace was just a cut down version of Nth Linux distro and I don't have a file server home that would benefit much from ZFS. Neither do I have to debug the exotic stuff you would want DTrace for.
