Thanks, I agree that ssh is overkill. I'd really like to understand
more about X credentials, wrappers, and the like. I've googled the
terms, but I only find technical information written for people
already familiar with the construct. Are there and resources that the
list could suggest, so that I will actually _understand_ what it is
that I'm doing when I use a wrapper, or change my X credentials?
