James, I can think of some optimization issue such as follows:

By running DHCPclient on the mobile while the mobile is using CDMA2000
RAN, one  uses PPP to  obtain an IP  address and DHCPclient  to obtain
other server parameters  and one needs to run both  the daemons on the
client to get fully configured. PPP has to happen and then DHCP. For a
rapidly moving client this may add to some optimization issue.

Thus if  the client is moving  between PDSNs this may  be bit overkill
but  may work  out  well if  the  same client  moves between  CDMA2000
network and WiFi for example.

Thanks
Ashutosh
