I think it is all hand-written, yes. Take a look at cpurc and what the options are. Most notably, the service directory, cpustart, and the plan9.ini file for tftp booting (iirc, I never tried it).

Well, it's designed for plan 9 systems, so you're probably out of luck on linux, except you try it with plan9ports.

While we're talking about finger, I wrote some simple android app called "FingerList" some time ago (on F-droid). It displays a list of fingers in a list format, it's intended for micro social networking with status pages and whatever people want to use it for.
