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.
