Thanks Mountie for kicking off this topic!

I don't think there is one answer for the best choice of notaries. It will
depend a lot on the use case and participants involved. Right now I imagine
that notaries will be used primarily for payments between financial
institutions. In this case the notaries could be the various FIs involved
in a particular payment. Or, some groups of FIs could choose to run
notaries as a service for one another. Another option would be to have well
respected hosting or other types of technology companies run them as a
service. The most important thing for participants is to choose a set of
notaries that builds in the right amount of fault tolerance for their use

Ryan Fugger also brought up the idea of using a blockchain as a notary
group. I think you could, though we haven't yet spent too much time
thinking about or working on this. Anyone interested in working on how to
do this?

I'm not sure I understand your questions about PKI and who trusts the
notaries. Notaries do need to sign their execute and abort messages so that
would involve using PKI. The connectors do need to trust a set of notaries.
Ledgers only need to trust the notaries if they are operated by licensed
parties operating in jurisdictions where the ledger operator would be
forced to cover payment risk (public distributed ledgers would not fit this
category as they are not operated by any entity that could actively decide
to trust some external systems).
