A fork of Matt's proposal converted to GF(2^8) is here: https://github.com/cetuscetus/btctool/blob/bip/bip-xxxx.mediawiki
Other changes include: - only six application/version bytes are allocated, which is the minimum to ensure that the encoded form starts with S in all cases; - encoded prefixes are SK/SL for a shared private key (mainnet/testnet) and SS/ST for a shared BIP32 seed; - the only hash function in use is SHA-256, which is the all-purpose hash function in the Bitcoin protocol; - double SHA is used for similarity with Bitcoin, although Jan and I believe single SHA is enough in this application; - bias-less encoding of M and x, because there can't be more than 255 shares over GF(2^8).
