I'm biased, but I'd like to see more discussions about the use of lawyers in custodial multsig set ups.  I think multi-institution is good, but using a lawyer adds lawyers of protection in terms of privacy.  For myself, literally hundreds of years fiduciaries have been custodying wills/trust instruments (see: any movie where they "read the will").  A key to a multisig is no different, particularlly when it's paired with a client's former last wishes.  I'm not a "Family/Trust/Estates Lawyer", but I am a fiduciary and there is a lot people in my profession can do to help people secure their secrets, wishes, and money so that they can rest easy until they rest forever. 

 I'd like to see this discussion, but with a focus on how smart contracts and blockchain can solve this...
