I don't know if we'll need to add sub-issues, or link to issues in other repos, but we discussed two potential changes:

1. Allowing absolute, in addition to relative, paths within the blessedSamples file so that we can point to services in external repositories. This may introduce a potential attack vector if a person is able to point to a repo with an insecure or malicious service, so we'll want to think this through.
2. Modifying the all-in-one installation script to have an optional override flag for the blessedSamples so that Adopters and Partners can create their own custom blessedSamples file that may live elsewhere. Again, we may want to consider how this functionality could be abused so that we don't introduce a vector for potential attacks.
