Actually, MIP4 simply defines the protocol for delivering the dynamic
address to the mobile node.  Whether it is handled by the HA through
an address poll, through interaction with a DHCP server etc, isn't
defined.  

People have implemented several different solutions, which all work;
this is good, and I don't see why we in discussing a draft laying out
the playing field have to go into details which hasn't even been 
specified by the base protocol (in the MIP4 case) ??
