At the moment, there aren't any plans for Steem. I don't agree with some of the actions made by Justin Sun and some of the witnesses and it's because of that I don't feel that building Quello around Steem would make sense. In the future, if collaboration with other blockchains makes sense this may be something we seek the opinion of the community on, however, at the current time I don't feel Steem would be a good move for Quello.
I'd love to hear your thoughts on the situation and what's taken place over the past couple of months on Steem.
