Actively looking into this.
Personally, I really, really want to see a Redshift - Blender plugin. I know there are alot of you out there that do as well. The Redshift development team needs to see that there is interest and people that really want to use Redshift within the Blender community.
If you are a current Redshift user, you WANT to use Redshift, or you would love to use a Blender - Redshift plugin, vote in my poll on Twitter.
