Check this out, perhaps it will help, if anyone actually had real private keys and real information:

And feel free to join our %100 multisig market, where public keys can be imported from external wallets (fully in your control) or generated by our market (we do not ever have the xprv key, it is generated on the client side - you can read the source-code if you know how).
Good luck,

So all the people saying BB wasn't "true" multisig were wrong? I thought their main point was that if BB exited, even with multisig the vendor is fucked.
