There's a lot of information here on my site on naming rules, jump service standards, ways to enable experimental naming services, revocation ideas, service directories, and so on. I also have some rules I could type up for name qualification, and a lot of data - for example, last uptime data for 1220 hosts. I wrote a couple hooks for experimental services two years ago - and they're almost unused, or even untried.
