	The two are mutually exclusive, Andrew!   DHCP is indeed a 
method for assigning dynamic IP's, but PPPoE is just what the name 
implies - it's a LINE protocol for controlling usage.

	PPPoE has a larger following for the simple reason that it 
allows ISP's to control (and more importantly TRACK) actual line 
usage.  PPPoE means that the ISP can dynamically drop your connection 
(usually when it's idle) and then you need to "redial" when you want 
to connect again.   And because they can track your connect time, 
they can (potentially!!) bill you per minute!


PPPoE - Just Say No!
