FYI, Shiva has been shipping a proxy DHCP client in our remote access
servers for about a year now (this is a proxy client, not a proxy
relay agent).  Finding a consistent way to make DHCP and PPP work
together is tricky because it depends a lot on the IP stack and PPP
client at the dial-in client end.  Our experience was that there were
a lot of limitations imposed by the stacks in terms of whether you
could give them an address after a certain point in their start-up,
whether the DHCP code could be made to wait for the PPP session to be
established before it tried to get an address, etc.
