Very similar to Tony F, I was sold on Hijack as soon as it provided a means to fiddle with VolAdj. Next were all those functions available from knob that normally require remote. Finally, there are ftp anf http daemons and all those useful /proc/* files. Ah, yes, I forgot remote key remapping: I just dug out a big old remote that happens to use the right code set; I will first try to define macros for key sequences I often use.

I currently don't use UI functions for userland programs, but plan to play with that a bit, too.
