The desktop sharing of skype has a long way to go to be used seriously. I can only assume from your comment that you haven't used it. They may have their audio codec down, and the video codec works for live video, but not for content. It's the same deal with JPEG for text for instance.
I'm really uncertain now of the future of Illumos and ZFS. I hope there's more push behind these projects as well as BTRFS. Will be interesting to see where this goes.
