The best client I've found is the Internet Systems Consortium (ISC)
DHCP client.  It's got plenty of script-programmable hooks, remains
running for the life of the interface, and follows the protocol
very tightly.

But Sympatico is PPPoE, not DHCP.  My parents use it, I run their
network, and they use PPPoE.  Sympatico's been that way for years.

This would be a *very very broken* DHCP server.  You *cannot* give out
a DHCP address if you've previously negotiated a lease for it with
someone else that is still in effect.  They're expected to renew their
lease well before it expires.

I'm assuming this is rhetorical humour (because it doesn't). :)
