It would appear we have an embarrassment of riches.
Someone correct me if I'm wrong but we have:
* nosh
* actual launchd with jkh's project
* now relaunchd
and of course some people like the flexibility and debugability of 
rc.d and are improving these.

Can someone more connected with these projects please sumarise what's
going on and maybe we can find a set of people with egos flexible enough
that we can maybe figure out the stengths of each of these and maybe 
make something truely great?
