There is no central authority -- it's fully decentralized. One person/device prepares the transaction, and whichever device adds/imports the last signature can broadcast it. It is passed around as ASCII-armored blocks of text that can be emailed, and/or copied to USB to take to offline devices. We would like to add a central server that would help users pass the data around, further improving the usability for those who want it... but the decentralized solution would always be available.

P.S. -- This is what people pass around to collect sigs (either inline in emails, or save to file):

A standard text format for "sig codes" that can be sent between users is what multisig needs.

Can this become a BIP? Something like this can become a standard that all the wallets and other services can support.

But, ...

Would it be better to use JSON clear text, so the user can see what tx/out/etc the sig refers to? Otherwise, users will get several sigcodes mixed up and go crazy.
