Can you explain in more detail what you are trying to achieve? SSSS works in principle with any arbitrary data, so you could certainly use a Bitcoin wallet file as the secret to be shared. You could also just use the wallet's encryption passphrase as the secret. – Nate Eldredge – 2014-09-14T02:35:02.503
@NateEldredge See this. Someone also recommended Blind signatures. I'm not really sure what the best way of implementing either of these schemes is, though. I wouldn't want to use the wallet's passphrase because I don't want the user decrypting the wallet to know the passphrase.
