Adept Secret Sharing (ADSS) by Bellare, Dai and Rogaway is a significant advance, hope more people consider it in future.
Though I don't think there is many implementations around.
That's a fair call, Shamir's secret sharing is pleasantly simple to use and understand.
Read the paper a while ago now but the scheme is still all fundamentally built on SSS, the auth, error checking and privacy layers are on top, so it's not a complete rework of what currently exists, more just some additions. Quite sure people have written some (perhaps all?) of these extras already in concert with regular secret sharing.
