If you want to then SPEND the funds sent in that 2-of-3 transaction... that isn't implemented yet

It kind of sucks... I thought it is already done... Can somebody slap RPC call for this??

$100 USD Bounty for this.

Spending funds from a 2-of-3 transactions works just fine, assuming all keys are available in a single wallet.

The problem is that obviously you do not want to require having all keys in one place - that would defeat the purpose. In what follows, a signature negotiation protocol (a la BIP10) will probably be suggested/implemented. The problem is not really the signing, it is rather communicating and coordinating among different wallets that requires an infrastructure that doesn't exist yet.

Let's say we have multi signature transaction.

How can sign through RPC transaction that moves money from multi signature one into some address?

For now, use a different private key for each multisig transaction, import the key when your ready to spend.

It's probably a good idea to get a product out there with this capability just to show it can be done.

Could not an online wallet be configured to perform such a transaction?

That's what I was thinking.  Even better, if we had a
Code:
bitcoind signfile filename.trans <address>
rpc command, the online wallet wouldn't have to hold the keys.  The wallet could just allows each user needing to sign to download the transaction in plaintext, run the command, and upload the result.  I don't know if they need to nest their signatures in a specific order or each sign the raw transaction, but the order could be enforced by the server if necessary.

While no idea is perfect, some ideas are useful.

No way this will be part of bitcoind. But it can be stand alone program with open source code.

Come on people, we have bounty for this.
