Do you have it laying around?  Maybe it would still be applicable.

I hear that.

What is wrong with the module stuff?  It looks pretty flexible to me.  It 
might be a little bit of work when talking to the objects via doit's, but a 
nice web/morph interface could be made for it.  At that point, it could have 
all the flexability of apache (maybe more) but in a much *much* friendlier 
way.  I have been setting up apache instances the last couple of weeks at 
work and those config files are a real bear.
