Unfortunately, I have not, although I assume it would be pretty easy, but you know what they say about those who assume things.
Actually I'm suddenly reminded of a conversation I had with the PALnet guys. I told them they should really turn the ability to upvote content with a HiveEngine token into a custom JSON operation instead of mirroring upvotes on Graphene. Turns out, that's a terrible idea because piggybacking off of Graphene was the entire point that makes the process so simple.
