This seems like an excellent initiative... especially if you can get it integrated with some of the Steemit based commerce initiatives like @steemgigs and @steemshop and @peerhub. One of the things (I believe) that will help Steemit become a more "solid" alt coin is having a viable Steem-based economy... and this could certainly help.
This is the idea! Hopefully this will add something useful to the Steem ecosystem. I've almost got "logging in" completed.
