Who can really trust intervening routers? It is after all, the Internet.
As for DNS, I (maybe too hastily?) trust my ability to recognize your IP
address when I see it.

Wow, the first update to that page in nearly four years!

I do have a GPG key on the MIT keyservers, but I've never bothered to get
it signed. Furthermore, I took GPG offline on a "temporarily permanent"
basis some time after I discovered that the signed messages I was sending
were not RFC-compliant. I do have a solution to the RFC-compliance
problem; I just haven't bothered to implement it yet. Other things I have
not yet bothered to do include setting up ssh-agent, which hopefully I can
figure out and do by Saturday's meeting, where I intend to scp what will
become my default SSH key onto the machine of your choosing. My current
SSH key is SourceForge-specific, hence the need for ssh-agent.
An example of what will no longer be possible is what happened at a recent
CABAL meeting: Somebody had a freshly installed Debian base system and had
a need for packages not allowed by the default sources.list as well as a
package from unstable (the system was tracking testing). After apt-get
installing SSH, I merely used my login to linuxmafia.com to scp over your
sources.list and /etc/apt/preferences to the new machine. Very handy!
