Well I’ve found a few more I plan to check out, and I’m going to give each at least a day’s worth of heavy coding, then narrow it down progressively until I finally decide on one. The non-free fonts that don’t look terribly promising I’m going to try and test drive online, but MyFonts anti-aliases things pretty heavily and indiscriminately, which makes it hard to tell how fonts work at smaller sizes. The new entrants in the contest are:

• MPW
• Monaco
• Profont and Sheldon
• Pica
• Pragmata
• Jet Jane Mono

Several of these font suggestions come via Aaron Swartz’s favorite fonts list. Personally I’d like to see more lists like this, perhaps in a semantically meaningful way that could be indexed and presented in different ways. Any format come to mind? I know I’ve read a couple of similar lists before, so I’ll try and dig up some more links.
