Payment protocol currently supports payments to multi-sig addresses. In general, almost all wallet software sucks RE multisig. Just try any of these actions in Bitcoin-Qt or another wallet: * obtain a public key you control, given a bitcoin address * easily share public keys * easily share partially signed transactions * build a P2SH multisig address from public keys, reliably. Right now, participants have no idea about pubkey order, leading various N possible P2SH addresses, given a list of public keys. Reproducing the P2SH address is harder than it should be. * track "partially controlled" balance (balance of coins of which you may sign at least 1 of N) * support for remote oracles and services that provide 1-of-N signatures etc.
