[HEADSUP & CFT] pkg 1.0rc1 and schedule

[Fbsd8]

What I want to know is this new pkg system going to remove the 
requirement of having the complete ports tree on my system?

What I am looking for in an port system, is to install a port and any 
files needed for the parent port and its dependents to automatically be 
downloaded. So in the end my system ports tree only contain the files 
used to install the ports I use and their dependents.
