Comcast is down at the Brohaus.
Obviously, that won't keep the hopelessly addicted from their Internet fix. I connected my N900 to my desktop and tethered. Then, I installed dhcpd and bind9, configured both, and (after some iteration on firewall rules) got network up and running for the other computers in the house. We're winners.
I made some good progress at work today on multiple projects. I am pleased with myself, although one thing that we did is (necessarily) a pile of ridiculous hacks upon other hacks. Still - they work (so far), so I'm not going to knock it.
