Here's a python implementation of Shamir's Secret Sharing Scheme: https://github.com/halfmoonlabs/secretsharing. Compared to all the other implementations I've seen, this library is actually quite easy to read and understand, which is huge IMO.
Well, maybe that is because you wrote it yourself "rxl"?
... actually is very easy to read. Even without knowing Python.

There's also Shamir's secret sharing iPhone app (https://itunes.apple.com/us/app/passbin/id718617728?ls=1&mt=8) that might be useful to the Bitcoin community, specifically to manage bitcoin and other cryptocurrencies account continuity.

Armory can do M of N backups and it uses SSSS:

Just ran across this thread... I believe this does add some key features to paper wallets. I started my thinking with Visual Cryptography, which is based on Shamir Secrets.

You could make a fairly robust paper bitcoin scrip scheme using this kind of crypto.

I haven't noticed that part of Armory. Could you drop me a link, thx!

Wouldn't it be by many factors more secure to apply Shamir's Secret Sharing Scheme on important private keys for decentralized offline storage?

It seems to me this would be the next step in offline / paper wallets.
Anyone know if any bitcoin wallet has built in support for something like this?
