is it useable in the client? i dont just mean multisig support so others can build it into a random client, i mean is it actually functional for users.

it seems very few coins have?

I think so.

This thread from 2013 gives some clients that supported multisig at the time.

Since then armory added it.

Electrum also supports it.

Does Electrum support sending to multi-signature addresses?
Yes Electrum does support sending to multisig addresses or P2SH addresses (addresses starting with '3').

Correct NEM has absolutely nothing unique about it apart from the fact its one of the biggest bullshitting coins in the altcoin world.

It is very useable. For both vanilla bitcoin transactions and smart property transfer.  You can use an intuitive web-wallet or a desktop client to use multisig.

CounterParty also supports paper wallets, deterministic BIP32 keys, Armory cold storage & Hardware signing like ledger wallet. In fact almost any security protection that can be afforded to regular bitcoin ecosytem, (like a kind of multisig 2fa where one signer is an oracle permitting set tx flows/rules) is possible since counterparty addresses are native bitcoin addresses.

If you'd like, you can play around with turing complete smart contracts interacting with multi-sig on testnet, since CounterParty can run ethereum serpent contracts right now.

Supercoin is super fast and super secure!

[funkenstein]

All of them. 

Who would clone from a repo that doesn't have multisig? 

Perhaps you can find a dead one lying around from 2012 that nobody updated but I doubt it.  All public coins have multisig as far as I know. 

[harry_weener]

Supercoin is 100% decentralized and trustless
What other multisig coins are 100% trustless?

[mrbodz]

all coins are. that's the whole point of crypto-currency.....

[harry_weener]

darkcoin has masternodes so i wouldnt call that 100% decentralized and trustless
correct me if wrong

[mrbodz]

okay masternodes are used for mixing. pow and the blockchain are still used for transactions so it is in a way
