I built a toy program some time ago that would monitor a daemon's state
using EVFILT_PROC filter in kqueue. My plan was a daemon that would run
under init, not replace it; and use the existing scripts in /etc/rc.d/
to actually start and stop services. 

Using a simple state machine and the code from rcorder to build a
dependancy graph I expect it could perform a parallelized boot. However
what I wanted was a system that restarts crashed daemons and had an
easy command line tool to monitor/enable or disable/etc your processes,
like the 'service' in Redhat or 'svcadm' in Solaris 10, but more.... 
BSD.
